A map can change the world, and so can you with the right resources. Maps We Love is an ongoing project to find and share inspiring examples of what’s possible with ArcGIS.

FLUXNET is a global network of micrometeorological tower sites that use eddy covariance methods to measure the exchanges of carbon dioxide, water vapor, and energy between the biosphere and atmosphere.

Archive contains fine spatial resolution translations of climate projections over the contiguous United States.

The ECOSTRESS mission is to measure the temperature of plants. The images acquired by ECOSTRESS are the most detailed temperature images of the surface ever acquired from space and can be used to measure the temperature of an individual farmer’s field.

ECOSTRESS data can be used in a wide variety of applications and applied science investigations, with partnerships on-going at the US and non-US federal, state, and local/regional scales.

Significance and process of Evapotranspiration. Explains changes during droughts.

This section of the Water Science School discusses the Earth's "natural" water cycle without human interference.

USGS Groundwater Data for the Nation

A distributed water database that is locally managed covers surface water, groundwater, and water quality data.

GROUNDWATER ATLAS of the UNITED STATES Idaho, Oregon, Washington

Data collected and managed by Forest Service programs is available in a map service and two downloadable file formats – in a shape file and an ESRI file geodatabase. Metadata is available that describes the content, source, and currency of the data.

A summary description for NGWA Pacific NW Expo – February 2012

“EEFlux” is an acronym for ‘Earth Engine Evapotranspiration Flux.‘ EEFlux is based on the operational surface energy balance model “METRIC” (Mapping ET at high Resolution with Internalized Calibration), and is a Landsat-image-based process.

MODFLOW is the USGS's modular hydrologic model. MODFLOW is considered an international standard for simulating and predicting groundwater conditions and groundwater/surface-water interactions.

The NGWMN is a compilation of selected groundwater monitoring wells from Federal, State, and local groundwater monitoring networks across the nation.

View over 13,000 USGS real-time stream, lake, reservoir, precipitation, water quality, and groundwater stations in context with current weather and hazard conditions. Data is refreshed every minute.

National Water Information System: Map View

Best available science to provide easily accessible satellite-based estimates of evapotranspiration (ET) for improved water management across the western United States.

The case study provides an example of the issues involved in allocating scarce water among diverse users and uses, and the difficulties policymakers face when attempting to design water allocation policies that require tradeoffs among economic, ecological, and societal values.

This website compiles USGS resources and data related to principal aquifers including Aquifer Basics, principal aquifers maps and GIS data, and the National Aquifer Code Reference List.

A repository of Earth Engines tools for planetary-scale platform for Earth science data & analysis. Google Earth Engine combines a multi-petabyte catalog of satellite imagery and geospatial datasets with planetary-scale analysis capabilities.

A web mapping tool to visualize community-level impacts from coastal flooding or sea level rise (up to 10 feet above average high tides).

The ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS), will monitor one of the most basic processes in living plants: the loss of water through the tiny pores in leaves.

The SSEBop setup combines ET fractions generated from remotely sensed MODIS thermal imagery, acquired every 8 days, with reference ET using a thermal index approach.

USGS Surface-Water Data for the Nation

The THREDDS server operated by the USGS Water Resources Mission Area supports the data serving portion of the Geo Data Portal and as part of the larger Data Integration Framework.

Precipitation, evaporation, freezing and melting and condensation are all part of the hydrological cycle - a never-ending global process of water circulation from clouds to land, to the ocean, and back to the clouds.

Interactive map to access real-time water data from over 13,500 stations nationwide.

View over 13,000 USGS real-time stream, lake, reservoir, precipitation, water quality, and groundwater stations in context with current weather and hazard conditions. Data are refreshed every minute.

These pages provide access to water-resources data collected at approximately 1.9 million sites in all 50 States, the District of Columbia, Puerto Rico, the Virgin Islands, Guam, American Samoa, and the Commonwealth of the Northern Mariana Islands.

State water-use data are reported by source (surface water or groundwater, fresh and saline, and total), category, and area type (county).

WHAT’S YOUR WATER FOOTPRINT?

It includes your tap water use and the “virtual water” used to produce

your food, electricity, gas and home goods.

Current conditions at selected sites based on the most recent data from on-site automated recording equipment. Measurements are commonly recorded at a fixed interval of 15- to 60-minutes and transmitted to the USGS every hour.

The Water Quality Portal (WQP) is the premiere source of discrete water-quality data in the United States and beyond.

Water information is fundamental to national and local economic well-being, protection of life and property, and effective management of the Nation’s water resources.
