Deliverable D2.2 Snow water equivalent data set

This report pertains to the Deliverable D2.2: Snow water equivalent data set, as described in ANNEX 1, part A (p. 32) of the EC/REA Grant Agreement for project number 101184962, “LIQUIDICE”. Work Package 2 of the LIQUIDICE project is led by NORCE with the support of CNR, IISC, IITB, GEUS, UNIVBRIS, SIOS-KC and IG PAS. Other beneficiaries are also asked to contribute to the deliverable by reaching out to key people and organisations in each of their own countries. The report provides a status for task 2.2 in LIQUIDICE. The task focus on measuring snow water equivalent using L-band SAR sensors. Since data from the NASA satellite NISAR was delayed in 2026, the task has focused on testing the retrieval method on ALOS-2 data. Additionally we investigate and discuss methods and datasets that can be used to validate the retrieval method and the products.
