KRMS (K(a)-band Radiometric Mapping System) GEOSAT - LIMEX '87 (Labrador Ice Margin Experiment) Data Products
Abstract
The K sub a - band Radiometric Mapping System (KRMS) was used to acquire high resolution passive microwave imagery of sea ice in the East Greenland and Labrador Seas during March 1987. Images obtain in the East Greenland Sea supported NORDA's GEOSAT ice index validation experiment (Chase and Holyer, 1988); Labrador Sea images supported the Labrador Ice Margin Experiment (LIMEX) (McNutt et al., 1988). In addition, we acquire several images sets that show open ocean in the North Atlantic Ocean and East Greenland Sea regions, glacial ice along the east central margin of the Greenland ice cap near Scoresby Sound, and land along the Avalon Peninsula of Nova Scotia. Farmer et al. (1988) provide navigation logs, track plots, KRMS system logs, and representative image samples for these data. Approximately 17 hours of imagery was recorded on analog tape. Most analog data subsequently were converted to digital format and recorded on computer compatible tapes at a density of 1699 bpi. The purpose of this report is to describe this digital product, to provide an index to tapes in the data archive, and to present an algorithm and a set of associated programs that were written to allow correlation between GEOSAT footprints and KRMS image segments that were collected along GEOSAT ground tracks. Keywords: Computer programs; Analog to digital converters; Ephemeris data.
