GLOBAL SUMMARY OF THE YEAR (GSOY) DATA FILES
|
||
(Last Updated: 1/15/2020)
|
||
|
||
1. INTRODUCTION
|
||
|
||
1.1 OVERVIEW
|
||
|
||
The Global Summary Of The Year (GSOY) Data Files contain quality controlled annual
|
||
summaries of more than 50 elements (max temp, snow, etc.) computed from stations in
|
||
the Global Historical Climatology Network (GHCN)-Daily dataset. These include non-US
|
||
stations, providing a global product from 1763 to present that is updated weekly.
|
||
This is not to be confused with GHCN-Monthly, which only contains temperature and
|
||
precipitation elements and which include bias corrected data (which are not available
|
||
in the first release of GSOM/GSOY). Annual averages in the GSOY Data Files are computed
|
||
from equally weighted months; (e.g, no weighting of months by number of days). This is
|
||
to remain consistent with the National Data Stewardship Committee’s recommendation
|
||
established in 2015. Annual values are set to missing if one or more data-months during a
|
||
data-year are missing. A description of the files are included below in Section 1.3.
|
||
|
||
1.2 ACCESS
|
||
|
||
The GSOY Data Files can be accessed at the following location:
|
||
|
||
https://www.ncei.noaa.gov/data/gsoy/
|
||
|
||
1.3 DOWNLOADING
|
||
|
||
There are three sets of individual files that are included as part of the HPD Digital Inventory Reports:
|
||
|
||
a. XXY########.csv (GSOY Station Data File Name)
|
||
|
||
XXY######## is the GHCN ID for the station in question, where:
|
||
|
||
XX = FIPS Country Code Two-Letter Identifier
|
||
Y = Station Network Code (Identifies The Station Numbering System Used)
|
||
|
||
Valid Station Network Codes:
|
||
|
||
0 = unspecified (station identified by up to eight
|
||
alphanumeric characters)
|
||
1 = Community Collaborative Rain, Hail,and Snow (CoCoRaHS)
|
||
based identification number. To ensure consistency with
|
||
with GHCN Daily and GSOY, all numbers in the original CoCoRaHS
|
||
ID have been left-filled to make them all four digits long.
|
||
In addition, the characters "-" and "_" have been removed
|
||
to ensure that the IDs do not exceed 11 characters when
|
||
preceded by "US1". For example, the CoCoRaHS ID
|
||
"AZ-MR-156" becomes "US1AZMR0156" in GSOY
|
||
C = U.S. Cooperative Network identification number (last six
|
||
characters of the GHCN ID)
|
||
E = Identification number used in the ECA&D (European Climate Assessment and Dataset)
|
||
non-blended dataset
|
||
M = World Meteorological Organization ID (last five
|
||
characters of the GHCN ID)
|
||
N = Identification number used in data supplied by a
|
||
National Meteorological or Hydrological Center
|
||
R = U.S. Interagency Remote Automatic Weather Station (RAWS)
|
||
identifier
|
||
S = U.S. Natural Resources Conservation Service SNOwpack
|
||
TELemtry (SNOTEL) station identifier
|
||
W = WBAN identification number (last five characters of the
|
||
GHCN ID)
|
||
|
||
######### = Actual Station ID (Format Is Dependent on the Station Network Code)
|
||
.csv = Comma-Delimited File Format Extension (can be opened in Excel, OpenOffice, etc.)
|
||
|
||
