In the last two decades, major drought events have occurred over the country, such as the 2010 and 2015 events in the Amazon, the 2012 event in the Pampa, and the 2014 event in the Cerrado biome. This research aimed to understand drought propagation and patterns over these biomes through joint analysis of hydrological, climatic, and vegetation indices based on remote sensing data. To understand the drought cascade propagation patterns, we assessed precipitation, evapotranspiration, soil moisture (at surface and sub-surface), terrestrial water storage, land surface temperature, enhanced vegetation index, and gross primary productivity. Similar drought patterns were observed in the 2015 Amazon and 2012 Pampa droughts, with meteorological and agricultural droughts followed by a hydrological drought, while the 2014 event in the Cerrado was more associated with a hydrological drought. Moreover, the 2015 Amazon drought showed a different pattern than that of 2010, with higher anomalies in precipitation and lower anomalies in evapotranspiration. Thus, drought propagation behaves differently in distinct Brazilian biomes. Our results highlight that terrestrial water storage anomalies were able to represent the hydrological drought patterns over the country. Our findings reveal important aspects of drought propagation using remote sensing in a heterogenous country largely affected by such events.<\/jats:p>","DOI":"10.3390\/rs15020454","type":"journal-article","created":{"date-parts":[[2023,1,12]],"date-time":"2023-01-12T03:11:02Z","timestamp":1673493062000},"page":"454","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Drought Propagation in Brazilian Biomes Revealed by Remote Sensing"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1458-9197","authenticated-orcid":false,"given":"J\u00falia Brusso","family":"Rossi","sequence":"first","affiliation":[{"name":"Institute of Hydraulic Research, Federal University of Rio Grande do Sul, Porto Alegre 91501-970, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3585-2022","authenticated-orcid":false,"given":"Anderson","family":"Ruhoff","sequence":"additional","affiliation":[{"name":"Institute of Hydraulic Research, Federal University of Rio Grande do Sul, Porto Alegre 91501-970, Brazil"}]},{"given":"Ayan Santos","family":"Fleischmann","sequence":"additional","affiliation":[{"name":"Mamirau\u00e1 Institute for Sustainable Development, Tef\u00e9 69553-225, Brazil"}]},{"given":"Leonardo","family":"Laipelt","sequence":"additional","affiliation":[{"name":"Institute of Hydraulic Research, Federal University of Rio Grande do Sul, Porto Alegre 91501-970, Brazil"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,12]]},"reference":[{"key":"ref_1","unstructured":"Hartmann, D.L., Tank, A.M.G.K., Rusticucci, M., Alexander, L., Br\u00f6nnimann, S., Charabi, Y., Dentener, F., Dlugokencky, E., Easterling, D., and Kaplan, A.
