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

This research paper evaluates Land-Atmosphere (L-A) interaction patterns in southeastern South America (SESA) by comparing satellite products (AMSRE-LPRM and MODIS) with climate and land surface models. The study confirms SESA as a significant L-A interaction hotspot, particularly within the Pampas ecoregion, and finds that these interactions are more intense and spatially extensive during dry summers compared to wet summers.

• Southeastern South America (SESA) is identified as a strong Land-Atmosphere (L-A) interaction hotspot across various metrics, temporal scales, and datasets, with consistency observed between climate models and satellite estimations. Specifically, both X and C bands of AMSRE-LPRM soil moisture products identify a strong L-A interaction hotspot over the Pampas ecoregion.
• The L-A interaction in southeastern South America is more intense and covers a larger spatial area during dry summers than during wet summers, a result observed in both satellite products and models.
• While C and X band soil moisture products identify the same L-A hotspot location, they differ in intensity, which is attributed to the characteristics of the ecoregions in that area.
