Scientists have conducted monthly oceanographic cruises to Station ALOHA, 100 km north of Oahu, Hawaii, since October 1988. The Hawaii Ocean Time-series (HOT) program collects measurements of thermohaline structure, water chemistry, currents, optical properties, primary production, plankton community structure, and particle export rates. This long-term dataset is managed by the OB_DAAC and is designed to characterize the North Pacific subtropical gyre.
Voyager 2 Plasma Wave Subsystem (PWS) electric field 16-channel Spectrum Analyzer data is provided for the entire mission in calibrated CDF files. The dataset is produced by the National Aeronautics and Space Administration. As of the release date, new data are accumulating.
Nine cameras on NASA's MISR instrument view each Earth location from different angles over seven minutes, enabling 3D cloud structure analysis. The data provides global coverage every nine days across four spectral bands centered at 443, 555, 670, and 865 nanometers. It is designed to monitor long-term trends in atmospheric aerosols, cloud types and heights, and land surface cover.

Geospatial data from the Dutch Ministry of the Interior indicates the probability of producing a given amount of thermal power at a location using a conventional geothermal doublet system. The dataset is provided via WFS, PNG, and WMS formats under a Creative Commons Public Domain Mark 1.0 license. Its last update date is unknown.
Geospatial boundaries reflect the noise zone limit of 50 dB(A) around five zoned industrial sites of regional importance. The data originates from the Dutch Ministry of the Interior and Kingdom Relations and is defined in relevant zoning plans. The delimitation of industrial sites was established by the concerned municipalities.
A geospatial representation of noise zones around five regionally important industrial sites, showing areas where sound levels exceed 50 dB(A). The data was produced by the Ministerie van Binnenlandse Zaken en Koninkrijksrelaties and is available in WFS, PNG, and WMS formats under a CC-PDM-1.0 license. The delimitation of the industrial sites was established by the concerned municipalities.
