Abstract. The Twente region in the east of Netherlands has a network with 20 soil monitoring stations that been utilized for validation Soil Moisture Active/Passive (SMAP) passive-only moisture products. Over period from April 2015 until December 2018, seven covered by SMAP reference pixels have fairly complete data records. Spatially distributed simulations Dutch National Hydrological Model de...

The evaluation of satellite soil moisture is a big challenge owing to the large spatial mismatch between pixel-based products and point-based in situ measurements. Upscaling measurements obtain “true value” content at grid/footprint scale can make up for difference improve validation. Many existing upscaling methods have strict requirements regarding distribution quantity sensors. However, real...

Streamflow is one of the key variables in hydrological cycle. Simulation and forecasting streamflow are challenging tasks for hydrologists, especially sparsely gauged areas. Coarse spatial resolution remote sensing soil moisture products (equal to or larger than 9 km) often assimilated into models improve simulation large catchments. This study uses Ensemble Kalman Filter (EnKF) technique assim...

Abstract The Joint Typhoon Warning Center (JTWC) utilized new space-based environmental monitoring (SBEM) data alongside traditional to adjust JTWC tropical cyclone (TC) intensity and structure estimates during production of the official 2019 Best Track dataset. Intensity from multiple platforms such as Advanced Microwave Scanning Radiometer-2 (AMSR2), Soil Moisture Active Passive (SMAP) Ocean ...

This paper describes a computation method for obtaining dielectric constant using Global Navigation Satellite System reflectometry (GNSS-R) products. Dielectric is crucial component in the soil moisture retrieval process reflected GNSS signals. The reflectivity circular polarized signals combined with equation that used radiometer observations. Data from Cyclone (CYGNSS) mission, an eight-nanos...

The assessment of seasonal streamflow forecasting is essential for appropriate water resource management. A suitable system requires the evaluation both numerical weather prediction (NWP) and hydrological models to represent atmospheric processes conditions in a specific region. In this paper, we evaluated ECMWF-SEAS5 precipitation product with four forecasts performed at hydropower plants Lega...

A thermal hydraulic disaggregation of soil moisture (THySM) algorithm was implemented to downscale NASA's active passive (SMAP) enhanced (SM) product 1 km over the continental United States (CONUS). This developed by combining inertia theory with a hydraulic-based approach that considers fine-scale SM spatial distribution driven both heat fluxes and conductivity in soils. Relative wetness value...
