Change in Monthly Surface Temperature Anomaly from Previous Month

Data:   CAMS surface air temperature anomaly  (deg. C) on a 2.0 x 2.0 deg. lat/lon grid Base Period for Climatology:  1971-2000 for land regions, 1974-present for ocean areas Data Source:  NCEP, Climate Prediction Center Description:  The change in surface air temperature anomaly from the previous month. Contours are drawn at intervals of 1.0 deg. C. Shading starts at +/- 1 deg. C as well. "CAMS" is an acronym for the "Climate Anomaly Monitoring System" in use at the Climate Prediction Center (CPC) at the US National Centers for Environmental Prediction (NCEP).
