XDD-938 Expendable Digital Radiosonde

The Model XDD-938 Expendable Digital Radiosonde conducts precise upper air observations using GPS wind finding technology. It is the first system capable of both radiosonde and dropsonde sounding modes, providing vertical profiles of 3D pressure, temperature, humidity and winds. It can either be released manually or used in the Model ARL-9000 launcher, which includes an integrated METHUB ground station.

MFR-7 Multifilter Rotating Shadowband Radiometer

The Model MFR-7 Multifilter Rotating Shadowband Radiometer measures total, diffuse, and direct irradiance at six wavelengths (415, 500, 615, 673, 870, and 940 nm, each 10 nm FWHM) in the visible/NIR, and includes one unfiltered broad-band silicon pyranometer. Thermally stabilized, environmentally sealed state-of-the-art interference filters provide excellent long term calibration stability.

TSI-880 Full-Color Total Sky Imager System

The Model TSI-880 Total Sky Imager is an automatic, full-color sky imager system that provides real-time display of daytime sky conditions. Traditionally, human observers reported sky conditions, resulting in considerable discrepancies from subjective observations. The TSI-880, a self-contained system which automatically processes images, replaces the need for these human observers under all weather conditions.
