What Nasa satellites say about Bangladesh’s climate

andrea.iervolino 13 February 2023

Nasa has declared 2023 as the year of open science. This leading space agency is making a long-term commitment to build an inclusive, open science community over the next decade. Open-source science is a commitment to the open-sharing of software, data, and knowledge (algorithms, papers, documents, ancillary information, etc) in a scientific process. The principles of open-source science are aimed at making publicly funded scientific research transparent, inclusive, accessible, and reproducible.

Shifts in regional water availability due to global tree restoration

andrea.iervolino 3 July 2022

Abstract

Tree restoration is an effective way to store atmospheric carbon and mitigate climate change. However, large-scale tree-cover expansion has long been known to increase evaporation, leading to reduced local water availability and streamflow. More recent studies suggest that increased precipitation, through enhanced atmospheric moisture recycling, can offset this effect.

New Global Groundwater Maps

andrea.iervolino 13 April 2020
NASA researchers have developed new satellite-based, weekly global maps of soil moisture and groundwater wetness conditions and one to three-month U.S. forecasts of each product. While maps of current dry/wet conditions for the United States have been available since 2012, this is the first time they have been available globally.
