Estimation of groundwater storage loss for the Indian Ganga Basin using multiple lines of evidence
Janardhanan, Sreekanth; Nair, Akhilesh Sivaraman; Indu, J.; Pagendam, Dan; Kaushika, G.S. (Journal article; Peer reviewed, 2023)We used remote sensing data, field observations and numerical groundwater modelling to investigate long-term groundwater storage losses in the regional aquifer of the Ganga Basin in India. This comprised trend analysis for ... -
Improving subseasonal forecast skill in the Norwegian Climate Prediction Model using soil moisture data assimilation
Nair, Akhilesh Sivaraman; Counillon, Francois Stephane; Keenlyside, Noel Sebastian (Journal article; Peer reviewed, 2024)This study shows the importance of soil moisture (SM) in subseasonal-to-seasonal (S2S) predictions at mid-latitudes. We do this through introducing the Norwegian Climate Prediction Model Land (NorCPM-Land), a land reanalysis ... -
Leveraging Soil Moisture Assimilation in Permafrost Affected Regions
Pradhan, Ankita; Nair, Akhilesh Sivaraman; Indu, J.; Makarieva, Olga; Nesterova, Nataliia (Journal article; Peer reviewed, 2023-03-10)The transfer of water and energy fluxes between the ground and the atmosphere is influenced by soil moisture (SM), which is an important factor in land surface dynamics. Accurate representation of SM over permafrost-affected ...
