Visible and Infra-Red Spin Scan Radiometer (VISSR)Entry ID: gov.noaa.ncdc.C00330
Abstract: The National Climatic Data Center (NCDC) has, in archive, both digital data and hard-copy images from early VISSR (Visible and Infra-Red Spin Scan Radiometer) sensors on board the early Synchronous Meteorological Satellites (SMS) and Geostationary Operational Environmental Satellites (GOES). VISSR was on two SMS satellites, SMS-1/2, and the first six GOES satellites, GOES-1/6. GOES-4/6 were ... equipped with the VAS (VISSR Atmospheric Sounder), which routinely produced VISSR data and vertical soundings through the atmosphere. The geographic area covered was North and South America, the Northern and Southern Atlantic Ocean, and the Northeastern and Southeastern Pacific Ocean. The data period was July 1976 through September 1988. The GOES geostationary platform repeated the same field of view every half hour. For severe weather, the VISSR data was obtained every 3 to 5 minutes for a small area containing the weather of interest. VISSR/VAS was a scanning radiometer, with channels in the visible and IR (10 to 12 micrometer region for VISSR data) portions of the spectrum. The sensor produced 1 km visible data at 6 bit precision and 8 km IR data at 8 bit precision. The documentation contained in VISSR data included earth location references. Sensor calibration information is available separately. The VISSR archive file consists of a series of VISSR frames, wherein each frame contains the visible and IR data from one complete view of the earth from one satellite. Each frame consists of a series of records containing the visible and/or IR data from one East-West scan; the full earth view includes about 16,000 visible scan lines (each containing 16,000 data values) and about 1,800 IR scan lines (each containing 3,800 data values). Each scan contains documentation.
Purpose: To make a wide range of climatic data available to researchers and the public.

Quality Dataset is as complete as practicable for the 1983/84 and 1984/85 seasons. During the main period of the study (December 1983-February 1985), Antarctic petrels and southern fulmars were censused on Filla, Hop and Buchan Islands, and the southern face of McNab Island. Reference Breeding Groups (RGB's) were established by marking out roughly rectangular areas using natural feathers as boundaries ... where possible. One area for fulmars and Antarctic petrels was marked out on each island. The birds and occupied nests within these RGB's were accurately counted. The RGB's were counted before and after each count in the other colonies. Calculations of nesting pairs were made on the basis of the ratios within the RGB's between numbers of birds and numbers of nests. Colonies were divided into discrete units for counting, and each unit was assigned a code number. The Hop Island censuses were conducted on 13 January 1984, 10 December 1984, 2 January 1985 and 3 January 1985. The Filla Island censuses were conducted on 28 December 1983, 29 January 1984, 5 January 1985 and 6 January 1985. The Buchan Island census was conducted on 10 February 1984. The number of chicks banded in the RGB's were used as a measure of breeding success, by expressing survival as a percentage of the number of pairs known to have attempted nesting. In 1983/84 chicks of both species were banded on 15 February (Filla Island) and 23 February (Hop Island). In 1984/85 Antarctic petrel chicks were banded on 2 February (Filla and Hop Islands) and fulmar chicks on 18 February (Filla Island) and 19 February (Hop Island). Plates of the areas counted are given in the documentation. Fulmars, Antarctic petrels and cape petrels were all counted simultaneously using the same census method.Results are logically consistent. Reference Breeding Group (RGB) areas were accurately measured, and are given to the nearest 0.1m.
