1.0 INTRODUCTION

SDR data sets are formatted into the Shared Processing Data Exchange Format (DEF) at FNOC. They are transmitted to NESDIS via communication satellite, and given a data set name to identify it on the NESDIS Computer (CEMSCS). There are approximately 14 orbits acquired during a 24 hour period. Data for at least a 24 hour period but no more than a 48 hour period shoud be resident on the CEMSCS direct access storage devices at any given time. SDR data from three of the DMSP satellites F10, F11 and F13 is currently being keep on the CEMSCS.

The format of the near realtime and archived SDR files changed in April 1997. This document describes the new format., in use since that date.

The basic format of the SDR dataset is one SDR Output Header Record followed by a series of records which each contain one scanline of data. Section 2.1.1 describes the format of the SDR Output Header Record, record #1. Section 2.1.2 describes the format of the scanline data, records #2-EOF.

2.1. 2 HEADER RECORD DESCRIPTION

The SDR Output Header Record contains six description blocks which are defined in terms of words consisting of a combination of 32-bits, 16-bits, and 8-bits.

2.1.2.1 DATA RECORD FORMAT DESCRIPTION

The data record consists of a Scan Header Block and SDR Data Block found in records 2 through the end of the data set.

The SDR Scan Header has the Scan Counter which is a binary number and the B-SCAN start time is in minutes from the beginning of the day (0 to 86,400). NOTE: There are no A-SCAN times associated with these data sets.

The Data Block format is based upon 64 view spots per SCAN and contains a Latitude/Longitude value along with 14 parameters of which one is a spare. All parameters such as ice concentration of 0 at the Equator are available for each of the view spots.
