ALOSE4

The Along Line Of Site Experiment (ALOSE) is a five-deployment campaign to observe the space and time structure and variability of atmospheric structure for different climate zones. The campaigns include the SGP ARM-site for the months of December, April, and July, 2013, the TWP ARM-site at Darwin Australia during September-October, 2013, and the University of Alaska Poker Flat Research Range (APRR) near Fairbanks AK during February 2013. All available atmospheric data at ground research sites (i.e., the ARM and PFRR sites) are used together with measurements from an ASSIST (Atmospheric Sounder Spectrometer for Infrared Spectral Technology) instrument to provide four-dimensional observations centered on the research site location. The observing systems employed include surface stations, radiosondes, AERI, surface Microwave Radiometer, and an ASSIST instrument which views the atmosphere at four local zenith angles (0, 30 45, and 60 degrees) and the four azimuth quadrants of the upward facing hemisphere (i.e., North, South, East, and West). The objective of the sponsor of these campaigns is the validation of mesoscale structure forecast by atmospheric prediction models. The data sets are also being used to provide detailed validation profiles for satellite hyper-spectral soundings obtained from the Aqua, Metop, and the SNPP satellites, which are being collected for these satellite overpasses of the ALOSE ground sites during the surface based data collection periods.
