1. AVHRR Pathfinder Atmospheres Extended (PATMOS-x)
In 2004, STAR invested in hardware to house and reprocess the entire AVHRR GAC record. PATMOS-x is one of the STAR AVHRR reprocessing projects.
PATMOS-x is continuation of the ORA PATMOS program in the 1990’s. The AVHRR is relevant sensor for climate given its long record, consistent spectral coverage and improving calibration.
PATMOS-x offers new products at a higher resolution from improved data. Where PATMOS only offered cloud amount, PATMOS-x provides a full suite of cloud properties and selected clear-sky products.
PATMOS-x products were developed to be physically consistent with those from EOS/MODIS. We are trying to achieve same consistency with NPOESS/VIIRS.
PATMOS-x leverages heavily off of the development efforts already funded for real-time product generation (i.e. CLAVR-x)
PATMOS-x speaks directly to the NOAA mission of Climate Variability
