GISS SURFACE TEMPERATURE ANALYSIS Summary By Sudarshan Balakrishnan Defined in the late 1970’s for the comparison of 1-D global models Earlier method covers 20º - 90º latitudes (Rationale presumed) Southern Hemisphere were sufficient for temperature change Global cooling after 1940 was small and .4ºC rise between 1880’s and 1970’s. Analysis method documented in Hansen and Lebedeff for stations separated by 1200 km. They were able to create a data set and obtained quantitative estimates of the error and global model, which was shown to have a realistic spatial and temporal variability. This error is the only addressed one due to incomplete spatial coverage of measure- ments. Other sources of error include meteorological stations. Many other such techniques have been implemented. Largest agreement in warming is it’s spatial distribution which grows large at desolate locations and with a different global pattern. The general rule to follow which includes warming suggests N.H > S.H. H.L > L.L and
