Cooperative Institute for Meteorological Satellite Studies (CIMSS) – Madison, WI88th AMS Annual Meeting

5th GOES User’s Conference – 23-24 January, 2008 – New Orleans, LAINTRODUCTION AND PURPOSEThe Advanced Baseline Imager (ABI) on GOES-R will represent a technological leap in weather and environmental satellite capabilities. Improvements over the current imager include 16 spectral bands, faster data rates, spatial resolution, signal to noise and calibration accuracy. Preparing users for what lies ahead is a task being tackled by various research groups. At the Cooperative Institute for Meteorological Satellite Studies (CIMSS) multiple data sets are being generated in an effort to meet the needs of various GOES-R Algorithm Working Group (AWG) science teams. Parallel efforts are underway to provide simulated Advanced Baseline Imager (ABI) data from both existing satellite assets and from the Weather Research and Forecasting (WRF) model. Simulations from the WRF are being produced at multiple resolutions / time intervals to simulate ABI scanning scenarios: 15 minute full disk and 5 minute Continental US (CONUS) capabilities. WRF model simulations are turned into ABI imagery using a forward radiative transfer model (Poster P1.68) that incorporates both clear and cloudy-sky properties and a reflected component for the shortwave and visible bands. Some simulated datasets contain simulated instrument effects such as striping, random noise, and navigation shifts (Poster P1.47). A sophisticated remapping technique is being used to simulate the ABI from MODerate-resolution Imaging Spectroradiometer (MODIS) data (Poster 1.35).

ABI SIMULATED FROM MODEL

ABI SIMULATED FROM SATELLITE

ABI will have a mesoscale mode that allows it to focus on a specific target every 30 seconds, without interrupting other aspects of the ABI scanning schedule. These images are from the WRF-model 667-m Mesoscale domain simulation and depict the beginning of a convective system forming in Oklahoma.

P1.87

Large, memory-intensive WRF model simulations were recently performed on a high-performance supercomputer at the National Center for Supercomputing Applications (NCSA) at the University of Illinois in Urbana-Champaign (See Poster P1.20). ABI data were simulated from 3 nested domains configured to represent the anticipated GOES-R scanning regions (i.e. full disk, CONUS, and mesoscale).

• Full Disk: 6-km horizontal resolution

• CONUS: 2-km horizontal resolution

• Mesoscale: 667-m horizontal resolution

Simulating ABI from current satellite data requires the use of three current instruments to simulate every band. This 16-panel, showing France, required MODIS, Meteosat, and AIRS. Other simulations have been done using just MODIS and include a Fire and Smoke Case, Mountain Wave Case, Convective Cloud Case, Daytime Cloud Case, and a Mexican Dust Case.

The 16 panel image comes from the WRF-model 2km resolution CONUS domain simulation, the full disk image comes from the 6-km resolution Full Disk domain. All of the simulated data are remapped to an

approximate ABI projection based on the ideal Geostationary view from 75 West at ABI spatial resolution.
