Satellite Imagery

GOES East, GOES West, Meteosat, and GMS Satellite Imagery

Updated 8/8/06

SKYTAP™ weather satellite imagery products are continuously updated. Marta Systems maintains dedicated GOES-West and GOES-East GVAR Direct Readout Groundstations to provide real-time imaging at the maximum scan rate of each spacecraft. Our groundstations generate over 110 custom sectors from the East and West spacecraft.

Since we operate our own groundstations, we can also create custom sectors for your needs.

In addition to our own custom sectors, Marta Systems makes all of the NWS satellite imagery from Noaaport available to Skytap subscribers. This includes world-wide coverage from approximately 85 degrees North to about 20 degrees South in composite images assembled from Goes West, Goes East, Meteosat and GMS.

Marta Systems software is required to access the weather satellite imagery service and display the products on personal computer systems.

GOES Satellite Sensor Characteristics:
Name/Res	Bandwidth (um)	Type	Detected Phenomena
I2/4km	3.78 - 4.03	Shortwave IR	fog/stratus, ice vs water, clouds over snow
I4/4km	10.2 - 11.2	IR	cloud top temp, sfc temp
I5/4km (West)	11.5 - 12.5	IR	cloud top temp, sfc temp
I6/8km (East)	12.2 - 13.8	Split IR	low level moisture
VS/1km	0.52 - 0.72	Visible Light	clouds, snow cover, haze, pollution
WV/8km	6.47 - 7.02	Water Vapor	synoptic patterns, mesoscale, upper winds
