Resource Abstract:
- description: The Global Historical Climatology Network - Daily (GHCN-Daily) dataset integrates daily climate observations
from approximately 30 different data sources. Version 3 was released in September 2012 with the addition of data from two
additional station networks. Changes to the processing system associated with the version 3 release also allowed for updates
to occur 7 days a week rather than only on most weekdays. Version 3 contains station-based measurements from well over 90,000
land-based stations worldwide, about two thirds of which are for precipitation measurement only. Other meteorological elements
include, but are not limited to, daily maximum and minimum temperature, temperature at the time of observation, snowfall and
snow depth. Over 25,000 stations are regularly updated with observations from within roughly the last month. The dataset is
also routinely reconstructed (usually every week) from its roughly 30 data sources to ensure that GHCN-Daily is generally
in sync with its growing list of constituent sources. During this process, quality assurance checks are applied to the full
dataset. Where possible, GHCN-Daily station data are also updated daily from a variety of data streams. Station values for
each daily update also undergo a suite of quality checks.; abstract: The Global Historical Climatology Network - Daily (GHCN-Daily)
