CLIMATE REANALYSIS PRODUCT INTERCOMPARISON OVER HIGH MOUNTAIN ASIATHERE IS A CRITICAL NEED TO PROVIDE THE SCIENTIFIC COMMUNITY WITH THE MOST UP-TO-DATE INFORMATION ON CLIMATE DATA AND DATA UNCERTAINTIES OVER HMA AS QUICKLY AS POSSIBLE. THESE DATA ARE CRUCIAL TO MAKING PROGRESS ACROSS ALL GLACIOLOGY (AND OTHER) DISCIPLINES WITHIN HMA AND IS A PREREQUISITE TO PROPOSING NEW DATA ACQUISITIONS OR GLACIER MELT TOOLS. HERE WE PROPOSE TO INCORPORATE ALL AVAILABLE REANALYSIS DATA INTO A SINGLE DATA PRODUCT TO PROVIDE THE BEST APPROXIMATION OF CLIMATE AND CLIMATE DATA UNCERTAINTIES OVER HMA AT MULTIPLE RESOLUTIONS. IMPORTANTLY THE MODEL IS PURPOSEFULLY FLEXIBLE SUCH THAT ANY NEW DATA AT ANY TEMPORAL OR SPATIAL RESOLUTION CAN BE INCORPORATED AND THE OUTPUT UPDATED RAPIDLY. THESE DATA ARE CRITICAL FOR QUANTIFYING THE SENSITIVITY OF CRYOSPHERICCHANGES TO CLIMATE CHANGE ASSESSING THE CAUSES OF REGIONAL CRYOSPHERIC CHANGES PREDICTING MAGNITUDES AND IMPACTS OF FUTURE CRYOSPHERIC CHANGES OR PARTITIONING THE CONTRIBUTIONS OF SNOW AND ICE MELT TO REGIONAL WATER RESOURCES
