Summary

Abstract:
DMSP OLS level 0 raw telemetry data are acquired on selective passes by satellite receivers located at McMurdo Station, Antarctica (77 degrees, 51 minutes S, 166 degrees, 40 minutes E.) and Palmer Station, Antarctic Peninsula (64 degrees, 46 minutes S, 64 degrees, 4 minutes W.) Generally, most of the Antarctic continent and its coastline are covered daily. Swaths are 2250 kilometers long and generally start or end over the extreme South Pacific Ocean adjacent to the Ross Sea. Continuous data collection at McMurdo Station began on 9 February 1991, and at Palmer Station on 18 January 1990. The band width for LF/LS (light fine/smooth) is 00.4 - 01.1um and the TF/TS (temperature fine/smooth) is 10.8 - 12.5um. The data resolution is 550 meters at crosstrack. Data are archived, processed for requesters, and distributed by the Arctic & Antarctic Research Center (AARC). Processing of the raw data will depend on the requirements of the requester, but a typical sequence might be as follows: + Reformat raw data for extraction; up to 10 missing scan lines can be interpolated by the software. + Calibrate the reformatted data to convert from brightness values to temperature values. + Apply the moisture/atmospheric correction. + Register selected data to the user-specified grid. + Transfer to user-specified medium. Some examples are tape, diskette, photographic product, or file format for electronic transfer. About 95 percent of the presently archived data is cataloged in our online directory. Data dropouts, caused by transmission interference due to solar flare activity, occur in some images; the processing software can smooth the data if fewer than 10 scan lines are missing. All archived images contain usable data. Processed data are binary byte arrays of user-defined size. Full spacecraft attitude correction and earth correction routines are applied to the raw data to create the products. Orbital elements, equator crossings, altitude and period of the spacecraft are generated for the raw data using the AARC scientific workstation. Data products can be gridded to a user-specified grid. Data are also available in raw form (10 bits of information stored in a 16 bit word) on DDS2 or DDS3 DAT cassettes or on DLT7000 tapes. Users would need access to an 4mm DAT or DLT7000 tape drive. An alternative method to access the digital archive is to use the Sun Workstations located at the AARC, Scripps Institution of Oceanography. AARC personnel can be contacted for access information. |
