NOAA Satellite Week 2015 Poster: CIRA GOES and JPSS RGB Product Development Updates for AWIPS II D2D and NCP

Thursday, February 26, 2015

With the introduction of the National Weather Service’s (NWS) Advanced Weather Interactive Processing System version 2 (AWIPS II), satellite imagery display fidelity has significantly improved from 256 colors (8-bit Red/Green/Blue (RGB)) to the possibility of over 16 million colors (32-bit with 24-bit RGB (True Color) and 8-bit overlay/transparency).  This allows greater diversity and flexibility in satellite imagery display.

AWIPS II has 2 satellite image display components or perspectives.  Display 2-Dimensions (D2D) has the same look and feel as AWIPS I D2D and is used primarily in the NOAA National Weather Service Forecast Offices.  The National Centers Perspective (NCP) has the same look and feel as NAWIPS and will be used  primarily in the NOAA National Centers.   True Color visualization was already available in the AWIPS II D2D but not in NCP.

The NASA Short-Term Prediction Research and Transition Center (SPoRT) -led Experimental Products Development Team (EPDT) has developed additional software needed to extend the D2D True Color resource and leverage the D2D python derived parameter calculation capabilities to provide on-the-fly application of RGB formulas to real-time AWIPS II satellite imagery.    This also allows users to manipulate RGB channels through custom python routines.

The National Center’s AWIPS II NCP RGB Development Team consists of  NCEP, CIRA, SPoRT and Cooperative Institute for Meteorological Satellite Studies (CIMSS) staff.  The group’s goal is to determine the best pathway to add True Color and derived parameter capabilities to the NCP leveraging the existing software infrastructure in D2D.
