Pacific Northwest Climate Maps

The Climate Impacts Group (CIG) provides these maps to show how four important parameters of climate - temperature, precipitation, snowpack, and soil moisture - vary over time in the Pacific Northwest (PNW) as a result of natural climate variability and climate change. These maps show climate anomalies associated with different patterns of climate variability compared to average conditions during 1915-2003. The data are derived from historical climate measurements, global climate model simulations, and a spatially-distributed hydrology model. The maps currently show historical data, but will soon feature global warming impact forecasting.
