VISSR sensor introduced modifications in the presence of large temperature gradients
Abstract
An investigation is conducted of the temperature field retrieved from GOES Visible and Infrared Spin-Scan Radiometer (VISSR) measurements for evidence of sensor-introduced modifications, in order to estimate the response time characteristic of the thermal IR channel. The response time of the VISSR is, at about 20 microsecs, rather large by comparison to the 8-microsec sampling interval; as a result, large temperature gradients are stretched over several IR pixels and modify their brightness temperature.
