Finally, I have formulas that calculate weighted temperature averages from the appropriate latitude zones for the globe and each of seven major latitude zones. The Tropics zone (30N-30S) covers about 50 percent of the global surface area centered on the equator, whereas the NH and SH each cover 50 percent of the global surface and average together to equal the Global average. Note that the Arctic zone temperature anomaly of -0.861C on 2019 December 27 is the lowest since -1.455C was estimated for 2018 March 17. For example, new buildings near an observation station can increase the night-time temperature readings. Latest Global Temp. Met Office, in collaboration with the Climatic Research Unit (CRU) at the University of East Anglia (UK), Goddard Institute for Space Studies (GISS), which is part of NASA (USA), National Climatic Data Center (NCDC), which is part of the National Oceanic and Atmospheric Administration (NOAA) (USA). The New Climate Dice. Anomaly 2010 INCR 0.4. Global records go back about 160 years, giving a long period from which to draw conclusions about how our climate is changing. Climate models are often run on monthly intervals and require monthly heat content and temperature fields to best produce climate forecasts. An anomaly indicates the difference from normal. Efforts are made to take these into account by factoring the uncertainty into global-average temperature calculations, which means we end up with a temperature range rather than one definite figure (Figure 1). Updated through 2021-11-09 (click to enlarge) The next graph shows daily zonal temperature anomalies, where "NH" is Northern Hemisphere (0-90N) and "SH" is Southern Hemisphere (0-90S). NOAA Global Surface Temperature Anomalies, Goddard Institute for Space Studies Surface Temperature Analysis (GISTEMP). At +1.9°C, the mean annual surface air temperature (SAT) anomaly for October 2018-September 2019 for land weather stations north of 60° N, relative to the 1981-2010 mean, is the second highest value (after 2015/16) in the observational record starting in 1900 (Fig. 1). I have a 6th column with pre-calculated area weights for each of the 361 latitude zones based on a spherical earth and summing to 100 for the entire globe.
