Na'urar Jin nesa
[gyara sashe | gyara masomin]Remote sensing data, such as satellite-derived measurements of soil moisture, evapotranspiration, and vegetation indices, can provide valuable information on the development and progression of flash droughts.[3] Remote sensing data can be used to assess the rapid response of ecosystems to flash droughts by analysing multiple ecological metrics derived from satellite observations. These metrics, such as gross primary productivity (GPP), net primary productivity (NPP), and leaf area index (LAI), can provide insights into the reactions of ecosystems to flash droughts from both vegetation physiological and structural perspectives.
