The Lab. specializes in designing highly specialized data processing science algorithms and in generating consistent, high quality and well characterized Climate Data Record (CDR) and Earth Science Data Record (ESDR) long term single- and multi-satellite data products in support of global change studies.


The Moderate Resolution Imaging Spectroradiometer, or MODIS, sensor resides aboard the Terra and Aqua platforms, offering a view the Earth's surface every 1-2 days. The MODIS sensor collects data within 36 spectral bands, ranging in wavelengths from 0.4 µm to 14.4 µm and provides us with imagery at a nominal resolution of 250 m at nadir for two bands, 500 m resolution for 5 bands, and the remaining 29 bands at 1 km.


Visible Infrared Imaging Radiometer Suite, VIIRS, a scanning radiometer, collects visible and infrared imagery and radiometric measurements of the land, atmosphere, cryosphere, and oceans. VIIRS data is used to measure cloud and aerosol properties, ocean color, sea and land surface temperature, ice motion and temperature, fires, and Earth's albedo. Climatologists use VIIRS data to improve our understanding of global climate change.


Vegetation Phenology and Vegetation Index Products from Multiple Long Term Satellite Data Records. The Vegetation Index and Phenology (VIP) Earth Science Data Records Project is a multi-institution effort lead by the University of Arizona and funded by NASA MEaSUREs.. The GAC data from the AVHRR sensors onboard the NOAA satellites from 1981 - 1999 and MODIS Terra from 2000-2015.

     These projects are supported by NASA Cooperative Agreements and Grants
