Rain check: The ClimaCell weather app alerts you to when it will rain in your town, down to the minute

August 14, 2019

Is a cloud about to burst in your immediate vicinity? Now there’s an easy and accurate way to find out.

ClimaCell, a four-year-old weather technology company based in Boston, “is on a mission to map all of the weather data in the world—and to become the “default microweather platform of the emerging technology.”

The firm—founded by a team of former military officers from the Harvard Business School and MIT Sloan—launched its weather app on August 12, offering meteorological notifications for exact locations in more than 50 countries.

It promises “street-by-street, minute-by-minute short-term forecasts, according to a report by The Washington Post.

But how does the company provide such on-target, on-time forecasts?

 ClimaCell has developed a global network of weather data that marries traditional observations of pressure, temperature, precipitation and wind with information drawn from wireless signals, satellites, connected cars, airplanes, street cameras, drones and other electronic sources, the Post reports. Millions of pieces of weather data can be derived from these technologies. It’s what the company describes as the “weather of things” (versus “the Internet of things).

This mix of data is fed into ClimaCell’s forecast models, operated in Boulder, Colorado The company created the NowCast model that gives highly specific, minute-by-minute forecasts out to six hours—as well as a longer-term model, known as CBAM, that produces forecasts out to six days.

These models are designed to provide forecasts to help businesses solve problems in which “extra accuracy” is needed, according to CE0 Shimon Elkabetz.

Many of the weather companies operating today, founded in the 1960s and 1970s, just take model forecasts from different governments, blend them, and use statistical techniques to try to make them better. But ClimaCell is creating its forecasts from scratch.

Elkabetz said early results on its accuracy are promising. Compared with government forecasts, “we’ve been able to improve almost every parameter in every time frame,” Elkabetz said.

ClimaCell has also created a software platform that allows its forecasts to be optimized and tuned to customers’ needs. Elkabetz said it can generate forecast output for any weather variable of interest, at any location and at different degrees of specificity.

The forecasts are updated or “refreshed” constantly, which is the “best way” to increase their accuracy, according to Daniel Rothenberg, ClimaCell’s chief scientist. “In our U.S. precipitation NowCast, we refresh [the forecast] end to end in under five minutes,” he told The Washington Post.

By comparison, the U.S. government model used for short-range precipitation prediction, known as the HRRR (high-resolution rapid refresh model) updates hourly.

To date, the company has worked with airlines, energy, and on-demand transportation companies, and even with the New England Patriots. JetBlue, initially a customer, was so impressed by the results that it became an investor.

“We’re trying to become the leading private company in the weather space,” Elkabetz said.

The app is available on the AppStore for iOS devices, and an Android version is to be launched in September. The app is free and does not contain advertisements, but ClimaCell does plan to charge for certain features, such as notifications for precipitation beyond a certain time.

Hen party: U.S. cities allow residents to raise chickens

July 20, 2018

Talk about “urban chic.” Or should we say “urban chick”? Cities from Ann Arbor, Michigan to Ft. Collins, Colorado, are voting to allow residents to raise backyard poultry, according to a July 19 report by Worldwatch Institute.

It’s a serious issue – it’s no yolk,” Mayor Dave Cieslewicz of Madison, Wisconsin commented when his city reversed its poultry ban in 2004. “Chickens are really bringing us together as a community. For too long, they’ve been cooped up.”

Raising backyard chickens is an extension of an urban farming movement that has gained popularity nationwide. “Fresh is not what you buy at the grocery store. Fresh is when you go into your backyard, put it in your bag, and eat it,” said Carol-Ann Sayle, co-owner of a five-acre farm in Austin, Texas. “Everyone should have their own henhouse in their own backyard.”

In Cedar Rapids, Iowa, raising chickens has been legal since August 30, 2010. Since then Cedar Rapids’ urban chicken ordinance has been used as a model for other municipalities nationwide. The ordinance—which Rebecca Mumaw of the advocacy organization, Citizens for the Legalization of Urban Chickens (or CLUC) helped to draft, provides the following guidelines:

  • Residents are allowed to keep up to six hens (no roosters) on single family dwelling properties;
  • Permits are required for an annual fee of $25;
  • Applicants for permits are required to notify their neighbors of their intent to obtain a permit and to complete an approved two-hour class on raising chickens in an urban setting (cost $10-$12);
  • Chickens must be kept in an enclosed or fenced area and secured from predators at night;
  • Henhouses must provide at least four square feet of space per bird and meet certain design requirements;
  • Chicken enclosures must be kept in the backyard—located at least 10 feet from the property line and 25 feet from neighboring homes;
  • Chickens must be provided with adequate food and water—and kept in a manner to minimize noise, odor, and attraction of pests and predators; and
  • Slaughtering of chickens is not allowed.

Indeed, Mumaw told the local newspaper, the Dispatch Argus, “Raising a limited number of egg-laying hens will allow residents to raise their own food, just as they do in vegetable gardens now.”

“Buying local” also provides an alternative to factory farms that pollute local ecosystems with significant amounts of animal waste – which can at times exceed the waste from a small U.S. city, a government report revealed last month. In the United States alone, industrial livestock production generates 500 million tons of manure every year. The waste also emits potent greenhouse gases—especially methane, which has 23 times the global warming potential of carbon dioxide.

Meanwhile, advocates insist that birds raised on a small scale are less likely to carry diseases than factory-farmed poultry, although some public health officials are concerned that backyard chickens could elevate avian flu risks.

The USDA is not yet providing specific figures on the number of chickens being raised in urban environments.
