ASCAT Soil Moisture
This report presents a proposal for a new discrete global grid (DGG) that is recommended for implementation within IPF's software for processing scatterometer data and generating soil moisture products. The new grid is to improve the current adapted sinusoidal grid used within WARP4.0. An overview of the three main methods for implementing DGG'S; partitioning, tiling and subdivision, is present...
متن کاملComparing soil moisture retrievals from SMOS and ASCAT over France
The first products derived over France in 2010 from the L-band brightness temperatures (Tb) measured by the SMOS (Soil Moisture and Ocean Salinity) satellite, launched in November 2009, were compared with the surface soil moisture (SSM) estimates produced by the C-band Advanced Scatterometer, ASCAT, launched in 2006 on board METOP-A. SMOS and ASCAT SSM products were compared with the simulation...
متن کاملAn evaluation of ASCAT surface soil moisture products with in-situ observations in southwestern France
A long term data acquisition effort of profile soil moisture is currently underway at 13 automatic weather stations located in southwestern France. In this study, the soil moisture measured in-situ at 5 cm is used to evaluate the normalised surface soil moisture (SSM) estimates derived from coarse-resolution (25 km) active microwave data of the ASCAT 5 scatterometer instrument (onboard METOP), ...
متن کاملSmos, Ascat and In-situ Soil Moisture: a Comparison over the H-saf Area
Remotely sensed soil moisture products derived from the Advanced SCATterometer (ASCAT) and from the Soil Moisture and Ocean Salinity (SMOS) radiometer are analyzed and compared. The comparison has been carried out within the framework of an activity aiming at validating the EUMETSAT Hydrology Satellite Application Facility (H-SAF) soil moisture products derived from ASCAT over Europe and North ...
متن کاملEconomic Prioritization of Watershed Management Projects Based on the Impact on Water, Soil and Plant Resources
In natural resources, economic evaluation is poor in terms of study due to the uncertainty of non-consuming value of resources. In the present study, the evaluation of water, soil and plant resources in watershed management projects and expert questioning was done to enable the projects to be evaluated and prioritized economically. Three sub-watersheds were selected from the Parcel A ...
