Studying recent hydroclimatic variability in Madagascar despite deficient measurement networks: use of CHIRPS and GRACE data at the scale of the Mahajunga province
<p>Given the lack of in situ hydroclimatic measurements and networks in Madagascar, the GRACE (2003–2016) spatial gravimetry data, combined with other satellite data such as CHIRPS rainfall estimates or fire monitoring using GFED products, make it possible to establish an interannual assessmen...

| Sumario: | <p>Given the lack of in situ hydroclimatic measurements and networks in Madagascar, the GRACE (2003–2016) spatial gravimetry data, combined with other satellite data such as CHIRPS rainfall estimates or fire monitoring using GFED products, 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, especially after 2007, but also a
time lag in the linear variations and trends of the Water Equivalent Height
as well as the number of detected fires (variable indirectly measuring the
pressure of deforestation by slash and burn agriculture).</p> |
