The dataset includes Mission Scientist, Instrument Scientist, and Weather Forecast reports, often with attachments, documenting the campaign to collect detailed surface precipitation measurements. Its cross-platform presence on Data.gov and NASA Earthdata signals its importance for satellite precipitation validation.
Video footage documents aircraft flights during the Global Precipitation Measurement mission's Integrated Precipitation and Hydrology Experiment. The dataset contains MP4 files from flights on June 6 and June 8, 2014, over the Southern Appalachians, Piedmont, and Coastal Plain of North Carolina. Files are processed to 12.5 times original speed and segmented into ~3.5-minute clips.
Aircraft-based Cloud Radar System data were collected to validate satellite precipitation measurements from the Global Precipitation Measurement mission. The dataset contains high-resolution profiles of radar reflectivity and Doppler velocity from flights over North Carolina during the Integrated Precipitation and Hydrology Experiment. Data files are available in netCDF-3 format for the period from May 3, 2014, through June 12, 2014.
TB3 Model Tipping Bucket rain gauges collected precipitation data from May 1, 2014 through June 15, 2014 during the GPM Ground Validation IPHEx field campaign. The campaign was designed to characterize warm season orographic precipitation regimes in the Southern Appalachian region, including the Piedmont and Coastal Plain of North Carolina. Data is provided by the National Aeronautics and Space Administration in ASCII-csv format for each gauge location.
This dataset contains 46 days of vertically-pointing X-band radar measurements from the GCPEx field campaign in Ontario, Canada during the 2011-2012 winter season. It includes radar reflectivity and Doppler velocity data collected to validate and improve satellite-based winter precipitation estimates from the Global Precipitation Measurement mission. The data is provided in netCDF-3 format by NASA.
Hourly rainfall accumulation estimates for central and northeastern Iowa from 1 May to 16 June, 2013. This dataset was created by NASA for the Iowa Flood Studies (IFloodS) campaign, combining ground-based radar measurements with simultaneous satellite overpass data to validate satellite precipitation products. Data are provided in gzipped ASCII files.
Rain gauge measurements were collected from 45 observation sites in the Southern Appalachian region as part of the Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign. This dataset supports the Global Precipitation Measurement (GPM) mission by characterizing warm season precipitation in complex terrain. Data are provided by NASA in ASCII-csv format.
Long-term freshwater quality monitoring data for over 14 sites in the Fraser River Basin. Environment and Climate Change Canada collected this data for the past 15 years or longer to assess status, detect emerging issues, and track regulatory effectiveness. The dataset includes measurements for nutrients, metals, major ions, and other physical-chemical variables.
Columbia River Basin freshwater quality data from over 13 monitoring sites for 15 years or longer. Environment and Climate Change Canada collected this data under a Canada-British Columbia agreement to assess status, trends, and regulatory effectiveness. The dataset includes measurements for nutrients, metals, major ions, and other physical-chemical variables.
Modelled Annual Rainfall Erosivity (R-factor) data supports soil erosion risk assessment in New South Wales. The dataset, provided by the NSW Department of Climate Change, Energy, the Environment and Water, contains mean annual values calculated across a year range commencing in 2001. Its landing page was last updated on 2026-05-17.
The GPM Ground Validation Doppler on Wheels (DOW) OLYMPEX V2 dataset contains mobile X-band radar observations from the Olympic Mountain Experiment campaign. Data were collected by the Center for Severe Weather Research using a dual-polarization, dual-frequency radar with a 60 km range to study orographic precipitation enhancement.

A 2026 study by Chaoqi Yang compares two methodological frameworks for mapping groundwater protection zones in Yulin City, northwest China. The research uses 16 hydrological datasets to construct an Analytic Hierarchy Process-Geographic Information System (AHP-GIS) framework and a machine learning framework combining Principal Component Analysis and Self-Organizing Map (PCA-SOM). The dual-framework approach serves as a prescriptive decision protocol for selecting methods based on management contexts, addressing transparency and objectivity trade-offs.
