Microclimates ~ Matt Haugland

To accurately predict weather, physicist Tzvi Gal-Chen once said, “it is believed that one needs to specify about ten million pieces of information about the initial structure of the atmosphere both vertically and horizontally… and to put it in a form that a computer can understand. This is not a simple task even in principle.”

Fog occurs in microclimates that are relatively cool and damp, such as this small valley near Llandovery, Wales, UK.

As a boy growing up near San Francisco, California, Matthew Haugland was fascinated by the temperature variations in his own yard that he could measure with a thermometer. As a college student studying meteorology in Oklahoma, he pursued his interest in forecasting “microclimates” by purchasing five acres of land – an unusual property where the land rose 37 feet with significant temperature variations – and he erected six weather stations equipped with surplus sensors donated by his faculty advisor, Ken Crawford. For his Ph.D., his original plan was to use an existing forecast model to forecast on his piece of land.

What Matt discovered was that existing forecast models ignored the meteorological mechanism that created the temperature variations. It was a fundamental assumption that was necessary for the models to function. So, his only option was to build his own model.

Small-scale temperature variations tend to be largest on clear nights with light wind.

In the beginning, his computer model only forecasted nighttime temperature on his property. Then he tested the model in another area where nighttime temperatures were known to be relatively cold, and discovered that the model performed well in forecasting temperatures elsewhere. 

It was then he realized his model could be very valuable for many other uses – from agribusiness to energy consumption. For example, citrus growers could mitigate risk by better frost forecasts and energy companies could better predict energy demand – to generate more power during peak times, thus avoiding the need to purchase energy at higher prices from other sources. What this meant statistically is that with every 1% improvement in temperature forecasts, a utility company could save $1 million.

One of Matt’s professors, Fred Carr, had heard about the Collegiate Inventors Competition and urged him to submit his model. He did so and, to his surprise, won the grand prize award for 2006 beating out impressive competition with breakthrough inventions in technology and medicine from America’s top universities. With the prize money, he was able to start his own company, NanoWeather, Inc.

SHAN: What is a microclimate?

MATT: A microclimate is a small area that has a different climate from the larger area around it. By "small area," I mean anywhere from a few tens of feet up to the size of a large city.

I think the best examples of microclimates are in the San Francisco Bay Area where I grew up. The average maximum temperature during July in San Francisco is 68 degrees (F). Just 25 miles to the east, in the San Ramon Valley (e.g., Danville, CA), the average high in July is 90. San Francisco averages 23" of rain per year, while Kentfield, about 10 miles north of the Golden Gate, gets more than double that amount.

There are many examples of smaller microclimates within cities. For example, the eastern side of San Francisco is often sunnier and about 5 degrees warmer than the western side. The San Fernando Valley, near Los Angeles, is much warmer than areas closer to the coast.

I have five acres of land here in Norman, Oklahoma, which is where I did the research behind the forecast model. On some nights, one side of it can be as much as 20 degrees warmer/cooler than the other side, only 600 feet away.

On the West Coast of North America, south-facing slopes (such as this one near Malibu, California) tend to have more precipitation than other areas, which makes them more green and forested.

There are even smaller microclimates if you want to get into botany and entomology. Microclimates that exist on the scale of a few inches can affect plants and bugs.

SHAN: What are the benefits of being able to forecast an environment closely?

MATT: There are many benefits, depending on who you are and what you do. If you are a farmer, you're likely in a different microclimate than the nearest airport (where most weather data and forecasts are for). A few degrees can be the difference between frost and no frost. Wine growers are especially sensitive to this. It is the variety of microclimates, after all, that allows California to produce so many different kinds of wine. Some grapes are extremely sensitive to temperature.

Wine grapes are very sensitive to weather. The type of grape and its location on the vineyard are selected to take advantage of each unique microclimate.

Wind farms tend to be built in microclimates that have unusually high wind speeds. Knowing the wind speed at their exact location lets them predict how much power they will generate.

For other types of energy companies, temperature is very important for predicting demand. If it's 85 degrees at the airport but 95 degrees where most people live, energy usage will be a lot more than expected.

Companies in a wide variety of industries have meteorologists on staff. But there's no way a single forecaster (or even a team of 100) could forecast for every microclimate they need to know about. So having an automated system that can forecast for hundreds of thousands of locations in a short period of time can save them a lot of time and money. It also can help the forecasters do their jobs better.

SHAN: How do you achieve optimum results and accuracy with your technology?

MATT: It is able to resolve microclimates as small as 300 feet across, so it can give a forecast for a precise location.

Automated forecasting systems are generally one of two things: a) low-resolution numerical models or b) statistical methods based on low-resolution model data combined with measurements from weather stations. The models are not very accurate because they assume the landscape is smooth and homogeneous. In other words, they assume microclimates don't exist. Statistical methods can represent microclimates, but only at locations with weather stations. That's why most forecasts are for airports.

My technology does not rely on statistics, so it works well everywhere. It uses the low-resolution models to determine the general, large-scale weather pattern. Then it uses physics to determine how the large-scale weather pattern will interact with each microclimate. So it has the advantages of both of the standard methods, but without either of their disadvantages.

NanoWeather, Inc., has diverse customers, from energy companies as Pacific Gas & Electric, to weather companies, including AccuWeather. Using the technology originally intended only for Matt’s five acres of land in Oklahoma, NanoWeather’s forecasts now reach approximately 200,000 paid subscribers and tens of millions of users around the world.

It is estimated that almost half of the world economy is sensitive to weather and climate. With climate change, these economical and timely forecasts are becoming even more important for weather sensitive industries, and the system’s unique design makes it easy to fit different customers’ needs.

Weatherwise Magazine has dubbed Matthew Haugland -
“Master of Microclimates.”

Project GRAD LA ~ Ford Roosevelt


Volunteers from Project GRAD (Graduation Really Achieves Dreams) Los Angeles fan out into a San Fernando Valley neighborhood, going door to door. They look like they are canvassing the community for an election, but instead of political flyers they carry “graduation contracts.” With a list of student names, they know the signatures they seek to obtain before the sun goes down – incoming sixth grade students to one of four middle schools that comprise a “feeder pattern” into San Fernando High School.

Leading the “Walk for Success” is Ford Roosevelt, President and Chief Executive Officer of Project GRAD Los Angeles. Among the volunteers are former graduates of the program, staff from Project GRAD headquarters in North Hollywood, and some pretty impressive funders that support the organization’s work–Michael Eisner included.

They can be very persuasive in getting students to sign the Agreement that states that they will stay in school and graduate from high school having completed a college-prep curriculum. Parents must also sign the contract and agree to support Project GRAD rules, which state that homework is completed on time, school attended every day, and classroom rules are obeyed. Mutual respect among students and teachers is also required. 

“We believe that a college education is a right, not a privilege,” explains Ford. 


For those students that participate, graduate from high school and maintain at least a 3.0 grade point average, the reward can be a scholarship to a four-year college. In a time when budget cuts to education are epidemic, this commitment by public and private sector partners, teachers and principals, parents and families, and community-based non-profits is an important step in increasing college graduation rates for first-generation students from low-income backgrounds.

Shan: How does the model for Project GRAD work?

Ford: The Project GRAD model is based on four inter-connected strategies for increasing student performance that are precursors to college: Academic Enrichment; Parent Engagement; College Awareness, Readiness, and Retention; and Community Partnerships.

Project GRAD works directly with students and parents in the North East San Fernando Valley to raise aspirations and help prepare students to graduate from high school and college. For us, that work begins as early as possible and involves providing wrap-around services as students move throughout the educational pipeline. These services include academic enrichment, tutoring, summer programs, a college readiness curriculum, and parent programs.

Shan: What are some of the innovative ways Project GRAD keeps students engaged on a regular basis?

Ford: One example, Project GRAD uses to get students on board early is an intensive 4-week summer institute for 7th and 8th graders focused on algebra and robotics. We know that algebra proficiency is a key indicator for college success.

After the first Project GRAD Los Angeles Algebra and Robotics Summer Institute, student readiness for Algebra was tested and every student placed well enough to enter Algebra I (and after one semester, 85% of students earned a “C” or better). According to former LAUSD Superintendent, Roy Romer, failure in algebra “triggers dropouts more than any single subject.”
Our robotics programs have nothing to do with whether or not the students we work with are not as smart as students in wealthier communities. It's more a matter of bringing additional learning opportunities to our students that are similar as those in wealthier communities, which are just expected and a common practice. We are trying to level the playing field and create the same opportunities for learning and support as happens within wealthier communities.

Students who do not pass Algebra 1 in the 9th grade, are less likely to graduate from high school, let alone attend college. And for those students who do pass, and go on to college, too many must take remedial math before they are ready for college-level math.

Following the second summer institute, 90% of students after one semester had earned a “C” or better in Algebra I (36% earned an “A”, 33% earned a “B,” and 21% earned a “C.”) The institute includes mornings devoted to learning algebraic concepts, and afternoons applying those concepts to building and programming Lego robots.
We continue to support our students, 90% of whom are the first in their family to attend college, through the community college and university level. In collaboration with several higher education partners, Project GRAD is working to create the systemic change necessary to enable more first-generation college students to persist once they make it to college.

Up to 160 students learn through hands-on, real-life applications of algebra to compete each year in the “Robot Olympics” at the conclusion of the 4-week intensive institute.

Project GRAD Los Angeles works with about 14,000 students in four middle schools and four high schools. Presently, 580 Project GRAD Scholars are enrolled in colleges and universities across the country.  Since 2005, 230 Scholars have earned their college degrees.

One of 10 Project GRAD sites across the country, Project GRAD Los Angeles was founded in 1999 with substantial support from The Eisner Foundation and The Ford Foundation.
