We don't do shallow water in my lab. In collaboration with friend and colleague Yongming Xu and others, we used coarse-resolution (MODIS) satellite data as well as point observations from weather stations in Tibet to map and monitor temperature trends across Tibet for the period 2001-2015. Below you see one result of that work - a map showing the 15-year mean near-surface air temperature across Tibet.
Compared to alternative data sets that provide the same type of information, we were able to show that our maps have dramatically lower errors, and are practically free of bias (consistent under- or over-estimation). Because we believe the data set we have produced will be useful to the community of people working on temperature and changes in Tibet, we have made it available to the public here.
