The temperature values are reported as "raw", % "adjusted", and "regional expectation". % % The "raw" values reflect the observations as originally ingested by % the Berkeley Earth system from one or more originating archive(s). % These "raw" values may reflect the merger of more than one temperature % time series if multiple archives reported values for this location. % Alongside the raw data we have also provided a flag indicating which % values failed initial quality control checks. A further column % dates at which the raw data may be subject to continuity "breaks" % due to documented station moves (denoted "1"), prolonged measurement % gaps (denoted "2"), documented time of observation changes (denoted "3") % and other empirically determined inhomogeneities (denoted "4"). % % In many cases, raw temperature data contains a number of artifacts, % caused by issues such as typographical errors, instrumentation changes, % station moves, and urban or agricultural development near the station. % The Berkeley Earth analysis process attempts to identify and estimate % the impact of various kinds of data quality problems by comparing each % time series to neighboring series. At the end of the analysis process, % the "adjusted" data is created as an estimate of what the weather at % this location might have looked like after removing apparent biases. % This "adjusted" data will generally to be free from quality control % issues and be regionally homogeneous. Some users may find this % "adjusted" data that attempts to remove apparent biases more % suitable for their needs, while other users may prefer to work % with raw values. % % Lastly, we have provided a "regional expectation" time series, based % on the Berkeley Earth expected temperatures in the neighborhood of the % station. This incorporates information from as many weather stations as % are available for the local region surrounding this location. Note % that the regional expectation may be a systematically a bit warmer or % colder than the weather stations by a few degrees due to differences % in mean elevation and other local characteristics. % % For each temperature time series, we have also included an "anomaly" % time series that removes both the seasonality and the long-term mean. % These anomalies may provide an easier way of seeing changes through % time. % % Reported temperatures are in Celsius and reflect monthly averages. As % these files are intended to be summaries for convenience, additional % information, including more detailed flagging and metadata, may be % available in our whole data set files. % % The Berkeley Earth analysis was run on 15-Nov-2013 19:55:48 % % Raw Data QC Continuity Adjusted Data Regional Expectation % Year, Month, Temperature, Anomaly, Failed, Breaks, Temperature, Anomaly, Temperature, Anomaly 1950 12 NaN NaN NaN NaN NaN NaN -0.468 -2.077 1951 1 NaN NaN NaN NaN NaN NaN 1.466 1.935 1951 2 NaN NaN NaN NaN NaN NaN 1.331 0.530 1951 3 NaN NaN NaN NaN NaN NaN 5.951 0.150 1951 4 NaN NaN NaN NaN NaN NaN 11.712 -0.076 1951 5 NaN NaN NaN NaN NaN NaN 16.799 -0.369 1951 6 NaN NaN NaN NaN NaN NaN 21.479 -0.337 1951 7 NaN NaN NaN NaN NaN NaN 24.400 0.096 1951 8 NaN NaN NaN NaN NaN NaN 23.148 -0.413 1951 9 NaN NaN NaN NaN NaN NaN 20.000 0.263 1951 10 NaN NaN NaN NaN NaN NaN 14.579 1.518 1951 11 NaN NaN NaN NaN NaN NaN 5.272 -2.018 1951 12 4.167 1.375 0 0 4.167 1.375 2.246 0.637 1952 1 4.278 3.565 0 0 4.278 3.565 2.520 2.988 1952 2 4.722 2.739 0 0 4.722 2.739 2.541 1.740 1952 3 5.722 -1.261 0 0 5.722 -1.261 5.014 -0.787 1952 4 13.611 0.641 0 0 13.611 0.641 12.679 0.891 1952 5 17.167 -1.183 0 0 17.167 -1.183 16.176 -0.992 1952 6 23.889 0.890 0 0 23.889 0.890 23.209 1.392 1952 7 25.944 0.458 0 0 25.944 0.458 25.369 1.064 1952 8 23.833 -0.910 0 0 23.833 -0.910 23.292 -0.270 1952 9 19.833 -1.086 0 0 19.833 -1.086 19.447 -0.290 1952 10 12.556 -1.688 0 0 12.556 -1.688 11.189 -1.872 1952 11 8.889 0.416 0 0 8.889 0.416 8.105 0.814 1952 12 3.611 0.820 0 0 3.611 0.820 1.969 0.360 1953 1 4.667 3.953 0 0 4.667 3.953 2.865 3.334 1953 2 5.500 3.517 0 0 5.500 3.517 3.494 2.693 1953 3 8.000 1.017 0 0 8.000 1.017 7.009 1.208 1953 4 12.944 -0.025 0 0 12.944 -0.025 11.891 0.104 1953 5 20.333 1.984 0 0 20.333 1.984 19.238 2.071 1953 6 22.444 -0.554 0 0 22.444 -0.554 22.052 0.236 1953 7 25.611 0.125 0 0 25.611 0.125 24.918 0.614 1953 8 24.611 -0.132 0 0 24.611 -0.132 23.374 -0.188 1953 9 21.056 0.136 0 0 21.056 0.136 19.942 0.205 1953 10 16.222 1.979 0 0 16.222 1.979 14.061 1.000 1953 11 8.833 0.361 0 0 8.833 0.361 7.807 0.516 1953 12 4.556 1.764 0 0 4.556 1.764 3.044 1.435 1954 1 NaN NaN NaN NaN NaN NaN -0.095 0.374 1954 2 NaN NaN NaN NaN NaN NaN 4.040 3.239 1954 3 NaN NaN NaN NaN NaN NaN 5.869 0.068 1954 4 NaN NaN NaN NaN NaN NaN 14.208 2.420 1954 5 NaN NaN NaN NaN NaN NaN 15.420 -1.747 1954 6 NaN NaN NaN NaN NaN NaN 22.059 0.242 1954 7 NaN NaN NaN NaN NaN NaN 24.290 -0.014 1954 8 NaN NaN NaN NaN NaN NaN 22.907 -0.654 1954 9 NaN NaN NaN NaN NaN NaN 21.167 1.430 1954 10 NaN NaN NaN NaN NaN NaN 14.920 1.858 1954 11 NaN NaN NaN NaN NaN NaN 6.346 -0.944 1954 12 NaN NaN NaN NaN NaN NaN 1.017 -0.593
