Smoke is in the Air
Jun 27, 2016       
We have the first evidence of smoke being present in the Ascension Island boundary layer from the LASIC [Layered Atlantic Smoke Interactions with Clouds] measurements from June 13 to 15. This indicates the surface-based measurements are picking up the signal of smoke present in the free troposphere and confirms the island is a good place [...]

BAMS Article Reports on a Data-Rich ARM/NASA Storm Clouds Campaign
Jun 20, 2016       
Midlatitude Continental Convective Clouds Experiment to be published in upcoming edition Convective clouds distribute water, heat, and momentum throughout the lowest layer of the Earth’s atmosphere, where weather happens. They get their name from the convective motion prompted when the surface of the Earth heats up, causing air to become buoyant and rise into the atmosphere. With [...]

Small ARM Campaigns Do Big Science, and You Could Too
Jun 20, 2016       
Next round of deadlines for small campaigns coming up; five recently approved campaigns span from Ascension Island to Mount Bachelor Not every science campaign requires a full deployment of ARM Climate Research Facility equipment; important work can be done with just an instrument or two, or in conjunction with a larger operation.

HI-SCALE: Introduction to the Team and Instruments
May 10, 2016       
We are into the second week of HI-SCALE, and have completed six research flights with the G-1 aircraft. Several people temporarily left the campaign earlier this week to participate in the ARM/ASR Principal Investigator’s Meeting in DC; however, we are in very capable hands. In addition to the ARM Aerial Facility (AAF) flight crew, we [...]

New Version of Interpolated Sounding VAP Released
May 09, 2016       
A new version of the Interpolated Sounding (INTERPOLATEDSONDE) value-added product (VAP) is released for use with historical data and current production. The INTERPOLATEDSONDE VAP transforms sounding data into continuous daily files on a fixed time-height grid at one-minute time resolution from the surface up to a limit of approximately 40 kilometers. The grid extends to [...]
