US Government Agencies
US Government (USG) agencies and programs offer various tools and data-sharing platforms that are accessible free of charge.
Coastwide Reference Monitoring System (CRMS) by USGS
The CRMS design includes a suite of sites encompassing a range of ecological conditions in swamp habitats and fresh, intermediate, brackish, and salt marshes. Approximately 390 sites are monitored using standardized data collection techniques and fixed sampling schedules.
Evapotranspiration Model (ET Demand) by USBR
The Bureau of Reclamation has collaborated with the Desert Research Institute and the University of Idaho in the development of a state-of-the-science computerized evapotranspiration (ET) model (ET Demands) that is being used to estimate historical and future agricultural irrigation water demands for the western United States.
Everglades Depth Estimation Network (EDEN) by USGS
Providing real-time hydrologic tools for biological and ecological assessments for adaptive management
The Everglades Depth Estimation Network (EDEN) is an integrated network of water-level gauges, interpolation models, and applications that generates daily water-level data and derived hydrologic data across the freshwater part of the greater Everglades landscape.
GLOBE Visualization System by NASA
Educational resources for schools and citizen scientists
GLOBE provides grade level-appropriate, interdisciplinary activities and investigations about the atmosphere, biosphere, hydrosphere, and soil/pedo-sphere, which have been developed by the scientific community and validated by teachers. GLOBE connects students, teachers, scientists, and citizens from different parts of the world to conduct hands-on science about their local environment and to put this in a global perspective.
Open source software for climate, weather and hydrology
The NASAaccess is an open-source R software package under NASA Open Source Agreement (NASA-1.3) that can access, format, and generate gridded ASCII tables of climate (CMIP6, CMIP5) and weather data (GPM, TRMM, GLDAS) needed to drive various hydrological models, such as SWAT, VIC, and RHESSys. NASAaccess package is part of NASA Applied Sciences program vision Improving Lives by Looking to Earth.
National Center for Environmental Information (NCEI) by NOAA
When it was established in 1961, the US National Oceanographic Data Center was the first such organization in the world. Today, including NCEI, there are national oceanographic data centers and similar organizations in approximately 50 countries including Argentina, Canada, France, Germany, the People's Republic of China, Russia, and the United Kingdom. In addition to data exchanges carried out through international organizations, NCEI also conducts direct bilateral data exchanges with data centers in dozens of countries.
NOAA National Weather Service: Southeast Asia Weather and Climate
NOAA produces weekly weather and climate guidance for Southeast Asia using a suite of numerical models that rely on observed and satellite data. Daily, 7-day and 30-day precipitation totals and max/min temperature charts are prepared using observed (GTS) data. NOAA’s Climate Prediction Center uses CMORPH (CPC MORPHing Technique) to produce a satellite-derived precipitation analysis at very high special and temporal resolution.
Reservoir and river modeling software by the University of Colorado Boulder
RiverWare is an advanced water resource modeling tool consisting of three sections: Simulation in RiverWare, Rule-based Simulation, and Multiple Run Management. RiverWare was developed by The Center for Advanced Decision Support for Water and Environmental Systems (CADSWES) at the University of Colorado Boulder, under joint sponsorship of the Tennessee Valley Authority, the Bureau of Reclamation and the US Army Corps of Engineers.
Geospatial data for development in the Lower Mekong
These decision support tools and applications have been developed to address on-the-ground issues, empowering decision-makers to act locally on climate-sensitive challenges such as disasters, agriculture, water management, ecosystem protection and land use.
Open Data Portal
Free and open geospatial data for the Lower Mekong region
The platform is built on ESRI technology with the goal of making geospatial data available to decision makers in the region in a format consistent with their operations. It is an open source platform that facilitates the creation, sharing, and collaborative use of geospatial data.
Surveying the world’s oceans
SWOT is being jointly developed by NASA and Centre National D'Etudes Spatiales (CNES) with contributions from the Canadian Space Agency (CSA) and UK Space Agency. The SWOT mission brings together two communities focused on a better understanding of the world's oceans and its terrestrial surface waters. US and French oceanographers and hydrologists, with international partners, have joined forces to develop this satellite mission to make the first global survey of Earth's surface water, observe the fine details of the ocean's surface topography, and measure how water bodies change over time.
Global Reservoirs and Lakes Monitor (G-REALM) by USDA
The Global Reservoirs and Lakes Monitor (G-REALM) provides time-series data on water level variations for some of the world's largest lakes and reservoirs. The G-REALM utilizes NASA/CNES/ESA/ISRO radar altimeter data over inland water bodies in an operational manner. The main database products are graphs and associated information in tabular form. G-REALM is hosted on the US Department of Agriculture (USDA) Foreign Agriculture Service website.
The Soil and Water Assessment Tool (SWATonline)
SWATOnline – A Web-based Decision Support Tool, is a modeling tool used by scientists to analyze many of the physical processes involved in the water cycle. SWATOnline is a web app that assists in using information and communication technologies to store, manage, and analyze water and climate data. The SWATOnline web app is generic and can be used globally, so more people can utilize SWAT model capabilities to access and visualize data. SWATOnline is part of NASA Applied Sciences program vision Improving Lives by Looking to Earth.
