HIGH-RESOLUTION ENHANCED PRODUCT BASED ON SMAP ACTIVE-PASSIVE APPROACH USING SENTINEL 1A AND 1B SAR DATA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
SMAP project released a new enhanced high-resolution (3km) soil moisture active-passive product. This product is obtained by combining the SMAP radiometer data and the Sentinel-1A and -1B Synthetic Aperture Radar (SAR) data.

Revisiting the hydrological basis of the Budyko framework with the principle of hydrologically similar groups [PDF]

Hydrology and Earth System Sciences, 2023
The Budyko framework is a simple and effective tool for estimating the water balance of watersheds. Quantification of the watershed-characteristic-related parameter (Pw) is critical for accurate water balance simulations with the Budyko framework ...

An Improved Unmixing-Based Fusion Method: Potential Application to Remote Monitoring of Inland Waters

Remote Sensing, 2015
Although remote sensing technology has been widely used to monitor inland water bodies; the lack of suitable data with high spatial and spectral resolution has severely obstructed its practical development.

Cooling water use in thermoelectric power generation and its associated challenges for addressing water-energy nexus

Water-Energy Nexus, 2018
Thermoelectric power plants traditionally have required huge volumes of water to condense steam from the turbine exhaust. The complex interdependency between water and energy poses new challenges for policy makers to achieve a safe, secure and ...

Mesoscale eddies heterogeneously modulate CO₂ fluxes in eddy-rich regions of the Southern Ocean [PDF]

Biogeosciences
Mesoscale eddies are known to influence the Southern Ocean biogeochemistry. However, the distinct contributions of cyclonic and anticyclonic eddies to air–sea CO2 fluxes, as well as their longer-term effects remain poorly studied. We present results from

Integrated modeling of blue and green water evolution in a headwater region of Chaohu Lake: Impacts of climate and surface environmental factors

Ecological Indicators
Understanding the dynamic changes of blue water (BW, surface and groundwater) and green water (GW, soil-stored rainfall used by plants via evapotranspiration) is essential for assessing water resource sustainability.

National forest carbon harvesting and allocation dataset for the period 2003 to 2018 [PDF]

Earth System Science Data
Forest harvesting is one of the anthropogenic activities that most significantly affect the carbon budget of forests. However, the absence of explicit spatial information on harvested carbon poses a huge challenge in assessing forest-harvesting impacts ...
