Short summary
PolarVPRM uses a diagnostic, remote-sensing-based approach optimized for polar regions to estimate net ecosystem CO2 exchange (NEE) between the high-latitude land surface and the atmosphere. PolarVPRM NEE shows close agreement with NEE observed from eddy covariance sites, relative to other models. Examination of per-pixel trends in PolarVPRM NEE and its drivers (North America north of 55 N, 2001-2012) indicate arctic greening and boreal browning in response to changing environmental conditions.
