In the renewed Aratos Earth Observation Data Platform the improved DSLF radiation index is added. The Downwelling Surface Longwave Radiation Flux (DSLF) is the result of atmospheric absorption, emission and scattering throughout the atmosphere and can be defined as the thermal radiation that reaches the surface in the thermal infrared range (4-100μm). Its unit of measurement is Wm-2.
As part of the radical renewal of the Aratos Earth Observation Data Platform, the improved NDVI (Normalized Difference Vegetation Index) is being integrated. The ND Vegetation Index is a derivative of satellite measurements in visible and intermediate infrared radiation spectrum, the purpose of which is to capture the existence of vegetation and its photosynthetic performance.
At a time when professionals are called to limit their movements in the interest of public health, important services still need to be rendered. Due to current circumstances, the use of accessible remote tools is deemed essential in order to carry out important tasks in the fields of Crisis Management, Homeland Security, Environmental Protection and others making extensive use of satellite services.
