Testing and integration of JPSS VIIRS aerosol EDR algorithms and evaluation of upstream/downstream effects using the Algorithm Development Library (ADL)

Abstract

The Visible Infrared Imaging Radiometer Suite (VIIRS) is an instrument on board S-NPP that was launched on October 28, 2011. A second VIIRS instrument will be on the next Joint Polar Satellite System (JPSS) satellite (J-1) that is planned to be launched in early 2017. VIIRS is a scanning radiometer that consists of 22 spectral channels with band centers from 412 nm to 12,050 nm. It collects imagery and radiometric measurements of the land, atmosphere, cryosphere, and oceans. The VIIRS data processing is done at NOAA Interface Data Processing Segment (IDPS) which is also responsible for creating all other atmospheric, land and ocean products from the other sensors on board S-NPP. The testing and integration of algorithm and Look-Up-Table (LUT) updates are done by using Algorithm Development Library, a test system that mimics the operational system. In this work we will present the testing and integration work conducted for Aerosol Environmental Data Record (EDR) Algorithm improvements. As Aerosol EDR is used in many downstream products, we will present the effect of Aerosol EDR updates on those products. We will also discuss the effect of changes to upstream VIIRS Sensor Data Record (SDR) and Cloud Mask algorithms on the Aerosol EDR products.
