The Real Cloud Wars: The $6 Billion Battle Over The Future Of Weather Forecasting

24 June 2019, Forbes - Susan Adams
For decades, private weather forecasting has been a cozy industry, dominated in the U.S. by AccuWeather, The Weather Company (founded as The Weather Channel in 1982 and bought by IBM for $2.3 billion in 2016) and DTN, which focuses on industrial concerns and was purchased by a Swiss holding company for $900 million in 2017.

But now a perfect storm of macro-trends—ever cheaper processing power, cloud computing, vastly improved AI and a proliferation of low-cost sensors—has opened up the field to a fresh crop of ambitious startups. In aggregate, they have raised hundreds of millions of dollars from investors, who think the incumbents look vulnerable to creative new business models.

The impact grows with the size of the concern. Xcel Energy, a Minneapolis utility with $11.5 billion in annual sales and a big wind-power division, saved its customers more than $60 million in fuel costs over seven years using private forecasts from Boulder, Colorado-based Global Weather Corporation.

Climate’s Troubling Unknown Unknowns

We can’t adapt to perils we can’t foresee. So we need to cut greenhouse gas emissions now.

April 21, 2019, The New York Times
Opinion by William B. Gail, CTO of Global Weather Corporation, Past President of the American Meteorological Society

Donald Rumsfeld famously popularized the term “unknown unknowns” in a 2002 news briefing when describing the challenges of linking Iraq to weapons of mass destruction. Troublingly, climate change may also be strewn with such unknowns, and they pose daunting tests for how we face the future.

One is choosing among policy alternatives. Should we minimize tomorrow’s risks now by reducing greenhouse gas emissions, or save money today and spend it on adapting to the effects of planetary warming once threats emerge more fully, like rising seas or prolonged droughts? The policy debate increasingly tilts toward adaptation. Continue reading this article by clicking here.


Global Weather Corporation Awarded Patent for Improving Weather Forecasts Using Vehicle Sensors

High-resolution forecasts based on innovative use of vehicle sensor data fill the autonomous vehicle weather gap by delivering reliable road weather and surface conditions information to enable safe navigation along any route worldwide

BOULDER, CO, April 9, 2019 – Global Weather Corporation, a leading provider of weather forecast data services for business applications, announced today that it has been awarded a patent for its method for improving weather forecasts by incorporating sensor data from vehicles.

Weather can vary over sub-kilometer scales, particularly in coastal areas, mountain regions, urban areas, and across valleys. This fine-scale variation is hard to predict using traditional weather models. Yet the demand for detailed weather information has grown rapidly with the proliferation of mobile devices capable of receiving weather information and with advances in highly autonomous vehicles. Users seeking reliable weather information for their specific location are often provided with forecasts from fixed-location weather station locations, not for where they actually are.

The newly patented method delivers an improved forecast that leverages the increased geographic availability of vehicle sensors capable of providing weather observations. The vehicle observations greatly augment what is available from traditional fixed-location weather stations operated by institutions and enthusiasts. The method enables a fine-scale estimate of typical, localized weather variability, from which more accurate weather forecasts can be generated.

According to Global Weather Corporation CTO and lead inventor on the patent, Bill Gail, “Many of the most demanding new weather use cases, such as driving decisions made by autonomous vehicle systems, require ever-better forecast quality and specificity. The novel methods addressed in this patent make that possible.”

CEO, Mark Flolid, added, “Our team of scientists continues to lead the industry by innovating to address the mobility industry’s toughest weather challenges. This patent is another example of Global Weather Corporation anticipating customer needs and advancing technology that will address major safety and operational issues for autonomous vehicles by forecasting hazardous road weather conditions for any road in the world.”

Global Weather Corporation Adds New Road Condition, Near Dry, to its RoadWX® Road Weather Forecast

— World Leader in Weather Data Services Provides Drivers and Autonomous Vehicles with More Precise Information about Road Surface Conditions than Ever Before —

aWhere and Global Weather Corporation Partner to Provide Growers with Premium Field-Level Weather Intelligence

BOULDER, CO, February 28, 2019 –Global Weather Corporation, a leading provider of weather forecast data services for the enterprise, mobility, energy, and media industries, announced today an enhancement to its RoadWX® road surface conditions forecast service. The RoadWX forecast can now distinguish between five changing road surface conditions – dry, near dry, wet, slush, ice/snow. The new condition, “near dry,” fills the important gap between non-dry and dry roads, providing more information about what lies ahead.

Bill Gail, Global Weather Corporation CTO and Co-Founder, noted, “The new ‘near dry’ road condition helps identify more precise, transitional conditions when road surfaces are neither clearly wet nor fully dry, such as roads that have some slightly wet portions.”

Designed for the mobility industry, RoadWX provides the world’s most complete and reliably accurate road weather forecast to increase safety and provide critical decision support information for connected and autonomous vehicles. Use cases include navigation planning, autonomous vehicle availability function, operational domain support, fleet management, and applications such as driver safety alerts. Typical users include automotive OEMs, Tier 1 location services and navigation platforms, infotainment service providers, fleet management solution providers, and driverless technology companies – all of which require locationbased road weather and road surface condition forecasts to prepare for potentially hazardous conditions on the route ahead.
