NCAR Global, 2-hourly Ground-Based GPS Precipitable Water
| DOI: 10.5065/047C-HV45
NCAR global, 2-hourly GPS precipitable water data are derived from ground-based GPS measurements of zenith path delay (ZPD) using three different resources, including the International GNSS (Global Navigation Satellite Systems) Service (IGS) tropospheric products (since year 1995), U.S. SuomiNet (UCAR/COSMIC) products (since year 2002) and Japanese GEONET (GPS Earth Observation Network) data (~1100 stations, 1997-2005).
The data are divided into two groups: one is from GEONET network, and the data are available from 1997 to 2005; the other one combines IGS and SuomiNet network, and the data are available since year 1995 and planned to be updated yearly.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
