Arctic-RIMS: A Regional, Integrated Monitoring System for Pan-Arctic

Water Cycle Studies GOALS

– Characterize Variability in Land-Atmosphere Water System (from 1960-)

– Assess Response of Ocean– Identify Sources of Change– Develop Real-Time Detection System

for Pan-Arctic Water Cycle

Collaboration of UNH, CU, UW, JPL, SHI, AARI, Ohio St., UDel

Framework for the Enhanced ArcticRIMS Data and Model Integration System

“Tracking the Water”

Source data: Mark Serreze (CU), Mike Steele (UW), UNH, and government agencies from around the pan-Arctic
