Land-atmosphere interaction patterns in southeastern South America using satellite products and climate models

The study identifies southeastern South America (SESA), specifically the Pampas ecoregion, as a strong land-atmosphere (L-A) interaction hotspot. Using AMSRE-LPRM soil moisture and MODIS land surface temperature products alongside climate models, the research found that L-A interactions are more intense and cover a larger spatial extent during dry summers compared to wet summers. While both X and C band soil moisture data identify the same hotspot location, they differ in intensity due to ecoregion characteristics.

• Southeastern South America (SESA) is consistently identified as a strong land-atmosphere (L-A) interaction hotspot across various metrics, temporal scales, independent datasets, and both climate models and satellite estimations, with the Pampas ecoregion specifically highlighted by AMSRE-LPRM X and C bands.
• Land-atmosphere interactions in SESA are more intense and cover a larger geographic area during dry summers than during wet summers, a result observed in both models and satellite products.
• While C and X band soil moisture products identify the same L-A hotspot location, they show differences in intensity linked to the characteristics of the ecoregion in that area.
