HDF5 Format for International Surface Pressure Data Bank v10.11

Earth Systems Research Laboratory, Physical Sciences Division
2 August 2011
Abstract
This document describes an extensive collection of sub daily to monthly surface and sea level pressure observations taken over land and ocean from the beginning of barometric observations to the present. The format is designed to allow traceability of observations from their original source archive to the ISPD and to permit direct feedback from data assimilation to the original source archives. A single ISPDB HDF5 file contains thirteen tables and fifteen subgroups/directories.
All unit specifications should be Udunits compliant
I. Common Fields
The following fields are present in every table except dataset index table.
1.Observation (Station) ID
Length 13
Character
This field is designated for an identifier that represents a fixed station for land data.
It represents a marine call sign or other marine identifier when present.
Missing: 9 x 12
2.Timestamp
Length 12
Character
This field describes the year, month, day, hour, and minute of the observation in the form YYYYMMDDHH.
3.Unique Observation Number Code
Length 7
Character
Minimum:0000001
Maximum:9999999
A unique number assigned to each observation at the same observation time (year, month, day, hour, minute). Combining with Year, month, day, hour, minute forms a unique ID of each observation. E.g., the second observation in the Data Bank for February 2 1895 1201 GMT has field 9 = 0000002, and a unique observation code of 1895020212010000002 . **Table 1 lists current know non-unique ID assignments. By combining these with latitude and longitude they become unique also.
Table 1. Non-unique ID stamps.

Missing: -99The following description came from ICOADS document. See http://icoads.noaa.gov/e-doc/lmr.
Table 7 lists current source ID assignments. Each SID may contain a single
deck or a mixture of decks, but each SID is generally constrained to a single
input format. This helps to identify the format of data stored in the LMR
supplemental and error attachments (see sec. 5)
[NOTE: For UK MDB data, e.g., both DCK and SID are required to
determine the supplemental format. To accommodate additional
SIDs, the true value and coded ranges were increased to 0:254
and 1:255 (see Table 1 for additional information).
