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. Measurements are available in CFradial netCDF-4 format from November 6, 2015, to January 15, 2016.
NASA's GPM Ground Validation Met One Rain Gauge IPHEx V2 dataset contains precipitation measurements from the Integrated Precipitation and Hydrology Experiment. Data were collected from September 11, 2013 to October 30, 2014 using Met One Model 380 tipping bucket gauges across the Southern Appalachians, Piedmont, and Coastal Plain of North Carolina. It provides quality-controlled precipitation amounts and interpolated rain rates at one-minute resolution to validate satellite observations and support hydrological modeling.
GCPEx campaign reports span from September 4, 2011, to May 11, 2012, with the core field experiment occurring from January 15 to February 29, 2012, in Ontario, Canada. The reports were filed by scientists to address shortcomings in the GPM satellite's snowfall retrieval algorithm by collecting microphysical properties and coordinating model simulations. Categories include Mission Scientist, Mission Manager, Instrument Scientists, Weather Forecasts, and Plan of Day reports, many with additional attachments.
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.
Greenland 5 km DEM, Ice Thickness, and Bedrock Elevation Grids, Version 1 provides a foundational geospatial dataset for the Greenland Ice Sheet. The National Aeronautics and Space Administration produced it under the PARCA program, synthesizing satellite radar altimetry, airborne laser mapping, and photogrammetric data. Ice thickness grids incorporate approximately 730,000 data points from airborne radar and echo sounder surveys conducted in the 1970s and 1990s.
HLSL30 V1.5 provides harmonized Nadir BRDF-Adjusted Reflectance (NBAR) data derived from Landsat 8 Operational Land Imager (OLI) sensors. The product offers 30-meter resolution global land observations with a revisit frequency of 1.6 to 3 days, processed through atmospheric correction, cloud masking, and spectral bandpass adjustment. This NASA-funded project was decommissioned in January 2022, with users directed to an improved V2 product.
The World Climate Research Programme's International Programme for Antarctic Buoys (IPAB) collected this dataset from a drifting buoy network across three Antarctic regions. It provides raw, non-interpolated measurements of buoy position, atmospheric pressure, air temperature, and sea surface temperature from 1995 to 1998. Data are organized as daily and three-hour averages, supporting research on sea ice dynamics and polar climate.
