Dataset Name

The name of the MSPPS orbital data set archived at CLASS. The name has the following format:

Processing-Center.Data-Type.Spacecraft-Unique-ID.Year-Day.Start-Time.Stop-Time.Processing-Block-ID.Source with each qualifier defined below:

Qualifier Details
Processing-Center Three characters identifying where the data was created. Recognized character groups are:NSS = NOAA/NESDIS - Suitland, Maryland, USANPR = NESDIS Product - Suitland, Maryland, USA
Data-Type Four characters identifying the data type, transmission method of original data, and the file format. Recognized character groups are:AABP= MSPPS AMSUA Orbital Binary AAOP= MSPPS AMSUA Orbital HDF-EOS FormatDMOP= MSPPS DMSP/SSMI Orbital HDF-EOS FormatABBP = MSPPS AMSUB Orbital BinaryABOP = MSPPS AMSUB Orbital HDF-EOS Format

Spacecraft-Unique-ID

 NK = NOAA-15 (NOAA-K)NL = NOAA-16 (NOAA-L)NM = NOAA-17 (NOAA-M)NN = NOAA-18 (NOAA-N)S7 = Air Force F13S8 = Air Force F14S9 = Air Force F15
Year-Day e.g. D79104, where "D" identifies this group as a Julian day delimiter, "79" identifies the year in which the spacecraft began recording the data set and "104" identifies the Julian day on which the spacecraft began recording the data set.
Start-Time e.g. S1355, where "S" identifies this group as a start time delimiter. "1355" denotes 13 hours 55 minutes UTC (to the nearest minute) and represents the time at which spacecraft recording began.
Stop-Time e.g. E1456, where "E" identifies this group as an end time delimiter. "1456" denotes 14 hours 56 minutes UTC (to the nearest minute) and denotes the time of spacecraft recording of the last usable data in the data set.
Processing-Block-ID There are two different formats for this id:1. e.g. B0016465, where "B" identifies this group as a processing block ID delimiter. "0016465" is a seven digit number identifying the spacecraft revolution (orbit) in which recording of this data set began and the revolution in which the recording of the data set ended (the first five digits identifying the beginning revolution and the last two being the two least significant digits of the ending revolution).2. e.g. B0016330, where "B" identifies this group as a processing block ID delimiter. "0016330" is a seven digit number identifying the spacecraft revolution (orbit) in which recording of this data set began (the seven digits identify the beginning revolution)
Source Fixed field with value NS designating that there was No Station.

UTC

Coordinated Universal Time (UTC) is the international time standard. It is the current term for what was referred to as Greenwich Meridian Time (GMT). Zero (0) hours UTC is midnight in Greenwich England, which lies on the zero longitudinal meridian. Universal time is based on a 24 hour clock, therefore, afternoon hours such as 4 pm UTC are expressed as 16:00 UTC (sixteen hours, zero minutes).
