Triton Powers Through Two Winters North of the Arctic Circle

Enables Puhuri to exploit wind potential in Arctic conditions

The Triton Wind Profiler manufactured by VaisalaOnline  —  Vaisala’s Triton Wind Profiler has shown exceptional performance across two winters in the northern reaches of Finland.

With two Vaisala’s Triton Wind Profilers measuring the wind for Finnish developer and operator Puhuri Oy, Vaisala has demonstrated the unmatched resilience of the system in extreme winter conditions and the strategic and logistical advantages of remote sensing for wind energy firms in cold climates across the globe.

BOULDER, Colo. — The budget process for fiscal year 2018, which begins Oct. 1, is now under way with this morning’s release of President Trump’s proposed budget blueprint.

This proposal will be more fully developed in coming months, with the administration providing more detail and then the plan undergoing revisions during negotiations with Congress.

The administration’s blueprint would increase spending for defense by $54 billion, with corresponding reductions in domestic spending, including scientific research.

The Arctic has been losing sea ice over the past several decades as Earth warms.

However, each year, as the sea ice starts to melt in the spring following its maximum wintertime extent, scientists still struggle to estimate exactly how much ice they expect will disappear through the melt season.

Now, a new NASA forecasting model based on satellite measurements is allowing researchers to make better estimates. Continue reading

What’s Up Mr. Pruit?

AMS Letter to EPA Head Pruitt on Climate Change & Comments

Screen Shot-PruittOnline  —  In a news interview recently, the EPA Administrator Scott Pruitt denied the science that underpins the science of climate change. The video was repeated many times in the USA and overseas.

Mr. Pruitt is a smart person and likely understands the realities of science, so one must wonder what would cause him to make such a statement. Speculation abounds in the news media (It’s politics? Transparency? BS?).

The American Meteorological Society (AMS) took a different view and sent him a letter yesterday (shown below) suggesting that he mischaracterized the science. (The letter is reformatted to be web-friendly, but the words are unchanged.)

NASA: Snow science in support of our nation’s water supply

The SnowEx Campaign

SnowEx Field Campaign: 4K B-roll From The P-3 Orion AircraftOnline  —  Researchers have completed the first flights of the NASA-led field campaign that is targeting one of the biggest gaps in scientists’ understanding of Earth’s water resources: snow.

NASA uses the vantage point of space to study all aspects of Earth as an interconnected system. But there remain significant obstacles to measuring accurately how much water is stored across the planet’s snow-covered regions.

The amount of water in snow plays a major role in water availability for drinking water, agriculture and hydropower. Continue reading
