Short summary
Given the lack of in situ hydroclimatic measurements and networks in Madagascar, the GRACE (2003–2016) data, combined with other satellite data or fire monitoring, make it possible to establish an interannual assessment of certain climatic and environmental covariations at the northwest scale of the country. The results show a negative trend in continental rainfall and water content, but also a time lag in the linear variations and trends of the Water Equivalent Height and number of fires.
