More Images and Data from the Suomi NPP (National Polar-orbiting Partnership)

VIIRS

Although it's very early in the activation process, thermal infrared imagery is now available from VIIRS on board the Suomi NPP.

CrIS

The Crosstrack Infrared Sounder (CrIS) signal processors were powered up on 7:48 EST on 20 January 2012. Calibrated radiance spectra were generated about 30 minutes after receiving the RDR data.

CrIS 900 1/cm brightness temperatures collected on 20 January 2012.

Raw data was received at SSEC via the NPP Atmospheres Product Evaluation and Test Element (PEATE) and then processed with the CrIS Calibration Algorithm and Sensor Testbed (CCAST), developed jointly by CrIS Cal/Val colleagues at UW and the University of Maryland Baltimore County to produce calibrated/geolocated radiance spectra. Sample figures show global images of 900 1/cm brightness temperature, and sample spectra.

SDR products were generated routinely by IDPS and available within another day. If the current schedule holds, the Cal/Val team will finish its early checkout phase, concluding with an upload of refined calibration coefficients, on 03 March 2012.
