METEOROLOGICAL INTERPRETATIONS OF THE IMAGES FROM NIMBUS 5 ELECTRICALLY SCANNED MICROWAVE RADIOMETER

摘要

The Electrically Scanned Microwave Radiometer (ESMR) on the Nimbus 5 satellite measures microwave radiation in a band centered at 1.55 cm. It scans perpendicular to the satellite motion from 50° to the left to 50° to the right in the 78 steps every 4 seconds pro¬ducing an image with a best resolution of 25 km.nIt is shown that these images can be used to delineate areas of rain over the oceans. This data can be used to approximate the location of fronts, the rain/snow boundary and secondary cyclogenesis.
