The 100-km SST Field and Accumulation Files from the NOAA TIROS/NSatellite SeriesEntry ID: OSDPD0036_43
Abstract: The 100-km SST field file consists of a specific set of information pertaining
to global latitude and longitude intersections. The 1-degree resolution file,
or 100-km field file includes the area from 180W through 179E longitude and 70S
to 70N latitude.
The 100-km SST field file is stored on disk as a direct access file accessed by
the Direct Access I/O (DAIO) subroutine package. It consists of ... one
documentation record (record number one of each file), followed by one record
for each latitude or row of the field. Each row consists of one seven-word (28
bytes) unit of information for each longitude of column forming a grid
intersection plus one seven-word unit containing the row number identification
and the date and time of the last analysis made for the field. The
documentation record is created from a namelist data set and displayed
in a namelist format, although it is stored as a binary DAIO record. Since the
documentation record required 632 bytes, the minimum SST field record size is
632 bytes. The maximum record size currently provided for is 10,108 bytes,
which is the 100-km field record size.
The 100-km SST Accumulation file consists of an archive of the 100-km SST
fields. The number of fields archived at any one time depends on the size of
the data set and is given in the directory. The first record is a directory
record which points the user to the position of the first record for each field
archived. A pointer to the latest field entered in the file is also provided.
The user must check each field to find the field for the time period of
interest. Record 2 is the first field in the accumulation file.
