File Naming convention has the following format:
<PROCESSING-CENTER>.<PROJECT-ID>.<VERSION>.<PRODUCT-TYPE>.<SENEOR-ID>.<SPACECRAFT_ID>.<YEAR-DAY>.<START-TIME>.<STOP-TIME>.< PROCESSING-BLOCK-ID>.<SOURCE>.<FILE-TYPE>
Where:
PROCESSING-CENTER = Processing-Center where the data were created. Length: 3 char. Domain:
“NPR” = NOAA/NESDIS Product – Suitland, Maryland, USA
PROJECT-ID = I dentifies the project name. Length: 4 Char. Domain:
"MIRS" = Microwave Integrated Retrieval System (fixed)
VERSION = The product's algorithm version number Length: 2 char. Domain:
"VO" to "V3"
PRODUCT-TYPE = Identifies the type of product. length: 3 char. Domain:
"SND" = Sounding-type products.
"IMG" = 2-dimensional surface and precipitation type products.
Note that the fimename convention covers two types of products, and each type includes a suite of individual products. For example, the "SND" file will contain three sounding profiles: T(z), Q(z), and Hy(Z), and the "IMG" file will contain 9 integrated and surface products: TPW, CLW, RR, SWE, Snow,Cover, Sea Ice, LSE, LST and IWP. This approach allows onefile to store duplicate geolocation and other auxiliary data for each individual product type.
SENSOR-ID = Short Name for the instrument used to derive the product. Length 4 to 5 char. domain:
"AAMH" = derived fromcombined AMSU-A and MHS data on POES/MetOp spacecraft.
"SSMIS" = derived from SSMIS data on DMSP.
"ATMS" = derived from ATMS data on NPP/NPOES
SPACECRAFT_ID = Spacecraft-Unique-ID. Length: 2 char. Domain:
"NN" = NOAA-18 (NOAA-N)
"SA" = DMSP Air Force F16
"SB" = DMSP Air Force F17
"M2" = MetOp-2
YEAR-DAY = 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. Length: 6 char. (5 characters for the date string, plus one for the “D” at the beginning). Domain: “D”+”YYJJJ”
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. Length: 5 char. (4 characters for the time string, plus one for the “S” at the beginning). Domain: “S”+”HHMM”
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. Length: 5 char. (4 characters for the time string, plus one for the “E” at the beginning). Domain: “E”+”HHMM”
PROCESSING-BLOCK-ID = 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). Length: 8 char. (7 characters for the orbit number, plus one for the “B” at the beginning). Domain: “B”+”XXXXXXX”
SOURCE = Identifies the data acquisition source. Length: 2 char. Domain:
“NS” = Fixed field designating No Station.
FILE-TYPE = File extension that indicates file type. Length: variable. Domain: “hdf”, “he4”, “netcdf”, “bin”, etc.
