Ice Temperature Profiles - Antarctica Datacube Hackathon

Description: The product “internal ice-sheet temperature” is composed by maps of internal temperature for the regions in which the Robin model is valid D5-2 [RD.9] along with the relative uncertainty estimation and a map of the quality of the estimation.
