Interview with Victor Pellet, CNES PostDoc, Paris Observatory

Describe experience relating to water and space technologies

I grew up in a country (France) where water is freely available. The drought in 2003 was considered a one-time event. I had no single lesson on climate change at school. Despite this background, I was raised aware of the links between social and environmental inequality on a global scale.

Space technologies in the detection, monitoring and management of groundwater

Global groundwater supplies

Groundwater accounts for 30% of Earth’s freshwater resources (Shiklomanov 1993) (Figure 1) and is estimated to globally provide 36% of potable water, 42% of irrigation water, and 24% of industrial water – indicating its significant value (Global Environment Facility 2021). Groundwater affords a host of benefits, from providing better protection against drought and microbiological contamination than surface waters, to being generally low cost and accessible to many users.

ARSET - Applications of Remote Sensing to Soil Moisture and Evapotranspiration


NASA's Soil Moisture Active Passive (SMAP) Satellite Mission is providing new soil moisture data, and modelling frameworks are providing new evapotranspiration data. This webinar series is intended to help participants learn about NASA soil moisture and evapotranspiration products and how to access and apply them for water resource management. Throughout the sessions, participants will learn how to monitor and manage water resources with techniques learned in training. The series begins with an introduction to satellite missions and useful data sets.

ARSET - Water Resource Management Using NASA Earth Science Data


This online course covers precipitation (rainfall and snow fraction), soil moisture, evapotranspiration, runoff and streamflow, groundwater, and lake level heights. Participants are introduced to a number of NASA data products.


Participants will be able to use NASA remote sensing observations and land-atmosphere models to:
