4STAR team on successful ORACLES 2018 deployment

4STAR was deployed on the NASA P3 during ORACLES 2018 based out of Sao Tomé. Here our team kept 4STAR operating great for the whole deployment. 

Roy presenting new concept idea of SEASTAR at Ames Innovation Fair

Roy is leading and presenting a new concept for a shipborne automated sunphtometer and sky radiance collector, SEASTAR, at the NASA Ames Research Center's annual innovation fair. Here he is demonstrating the use of a handheld sunphotometer 'microtops' to a group of NASA Ames colleagues.

New partners with NRC Canada - 4STAR integrated onto the Convair 580

We formed a new partnership with the Canadian National Research Council. We sucessfully integrated 4STAR onto their Convair 580, for sampling during a Canadian Oil Sands project. 

Calibrating away at Mauna Loa Observatory

4STAR, 4STARB, and AATS are standing tall at the Maun Loa Observatory, at 11000 ft altitude within the remote Pacific Atmosphere, where the nearly pristine environment, with low aerosol optical depth, is used for calibrating our measurements.

Sunphotometer family reunited at Ames after many campaigns

4STARB's first flight campaign successful!
