This paper examines two new methods to generate gridded agricultural Gross Domestic Product (GDP) and compares the results with a traditional method. In the case of Brazil, these two new methods of spatial disaggregation and cross-entropy outperform the prediction of agricultural GDP from the traditional method that distributes agricultural GDP using rural population. The paper finds that the best prediction method is spatial disaggregation using a regression approach for all the key crops and contributors to agricultural GDP. However, the issue of degrees of freedom is an important limiting factor, as the approach requires sufficient subnational data. The cross-entropy method with readily available spatially distributed crop, livestock, forest, and fish allocation far outperforms the traditional method, at least in the case of Brazil, and can operate with national- and/or subnational-level data.

This book celebrates the ten-year anniversary of the Barcelona Expert Center by presenting recent contributions related to the topics on which the team has been working during these years. The Barcelona Expert Center expertise covers a wide variety of remote sensing fields, but the main focus of the research is on the Soil Moisture and Ocean Salinity (SMOS) data processing and its ocean, land, and ice applications. This book contains 14 scientific papers addressing topics that range from the description of the new data processing algorithms that are implemented in the last version of the operational SMOS Level 1 processor, to scientific applications derived from SMOS: results on the sea surface salinity assimilation in coastal models; synergies of the sea surface salinity with temperature and chlorophyll, and their impact on the better retrieval of ocean surface currents; quality assessment of SMOS derived sea ice thickness; sea surface salinity; and soil moisture products, among others. Moreover, one of the papers verifies the potential of the future CIMR mission within the CMEMS SSS operational production after the SMOS era.
Research & information: general --- Geography --- soil moisture --- root zone --- SMAP --- SMOS --- MODIS --- climatology --- trends --- signal decomposition --- interferometric radiometry --- image reconstruction --- error correction --- surface currents --- mediterranean sea --- satellite altimetry --- sea surface temperature --- sea surface salinity --- BEC SMOS products --- Mediterranean Sea --- Algerian Basin --- ABACUS gliders --- microwave remote sensing --- CIMR --- copernicus marine service --- satellite observations --- tidal currents --- internal tides --- data assimilation --- 4D-Var --- Congo River plume --- satellite salinity --- Angola Basin --- ROMS --- moisture variability --- temporal dynamics --- moisture patterns --- spatial disaggregation --- Soil Moisture Active Passive (SMAP) --- Soil Moisture and Ocean Salinity (SMOS) --- REMEDHUS --- L-band radiometry --- Soil Moisture and Ocean Salinity (SMOS) mission --- sea ice thickness --- retrieval model validation --- upward looking sonar --- Arctic --- altimetry --- surface quasi-geostrophic equations --- remote sensing --- ocean color --- data fusion --- data merging --- physical oceanography --- singularity analysis --- faraday rotation angle (FRA) --- vertical total electron content (VTEC) --- L-band --- radiometry --- Interferometry --- ocean salinity (SMOS) --- calibration --- reprocessing --- BEC --- oceanography --- cryosphere --- processing --- sensor calibration
