Gravity Instruments

Gravity instruments are those used in determining the size and shape of the Earth. They have become one of the most useful tools in geophysical prospecting and in geological studies. (Hoskinson 1936)

Urban Water Scarcity: How data from NASA’s GRACE-FO Mission can be used for (near) real time water management

As population becomes larger the demand for water soars, including water needed for domestic, industrial and municipal uses (Mogelgaard 2011). One example of that, is India, where on 20 June 2019 the city of Chennai almost run out of water. Satellite images show the extent of the water shortage in the city (figure 1). While people are queuing up to get water from water trucks that transfer water to the city, the greatest struggle is taking place in the city’s municipal buildings and businesses. Hospitals are facing the threat of not having enough water to treat patients and to clean equipment, and businesses are forced to shut down and wait until the crisis is over.

Global Precipitation Mission: Improved, accurate and timely global precipitation information

Continuous and reliable global precipitation information is crucial for myriad of weather, climate and hydrological applications. The importance of precipitation in the form of rain, hail, sleet, snow etc. is known to science and clear to a layman. However, it’s quite tricky to measure past precipitation trends or predicting accurate future forecasts. There are three main categories of precipitation data sets available: ground based, satellite-based and blended products of ground and space data (Climate Data Guide, 2014).
