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 2002 2 NaN NaN NaN NaN NaN NaN 6.004 1.280 2002 3 NaN NaN NaN NaN NaN NaN 9.982 0.737 2002 4 NaN NaN NaN NaN NaN NaN 17.573 2.818 2002 5 NaN NaN NaN NaN NaN NaN 18.918 -0.371 2002 6 NaN NaN NaN NaN NaN NaN 24.658 1.608 2002 7 NaN NaN NaN NaN NaN NaN 26.677 1.490 2002 8 NaN NaN NaN NaN NaN NaN 25.791 1.116 2002 9 NaN NaN NaN NaN NaN NaN 22.793 1.569 2002 10 NaN NaN NaN NaN NaN NaN 15.920 1.168 2002 11 NaN NaN NaN NaN NaN NaN 9.494 -0.012 2002 12 NaN NaN NaN NaN NaN NaN 4.122 -0.559 2003 1 NaN NaN NaN NaN NaN NaN 1.883 -1.504 2003 2 4.000 0.054 0 0 3.908 -0.038 3.827 -0.896 2003 3 10.667 2.199 0 0 10.575 2.108 11.135 1.890 2003 4 14.167 0.189 0 0 14.075 0.098 14.912 0.158 2003 5 17.778 -0.734 0 0 17.686 -0.826 18.714 -0.575 2003 6 21.833 -0.439 0 0 21.742 -0.531 22.478 -0.572 2003 7 24.389 -0.021 0 0 24.297 -0.112 25.249 0.062 2003 8 24.778 0.880 0 0 24.686 0.789 25.832 1.157 2003 9 19.889 -0.558 0 0 19.797 -0.650 21.306 0.081 2003 10 14.278 0.304 0 0 14.186 0.212 14.668 -0.083 2003 11 12.611 3.882 0 0 12.519 3.791 13.444 3.938 2003 12 4.389 0.485 0 0 4.297 0.394 4.245 -0.435 2004 1 1.833 -0.777 0 0 1.742 -0.869 2.488 -0.899 2004 2 4.056 0.109 0 0 3.964 0.018 3.473 -1.251 2004 3 10.556 2.088 0 0 10.464 1.997 11.002 1.757 2004 4 14.611 0.634 0 0 14.519 0.542 15.655 0.900 2004 5 21.500 2.988 0 0 21.408 2.896 22.297 3.007 2004 6 22.889 0.616 0 0 22.797 0.525 23.644 0.594 2004 7 25.000 0.590 0 0 24.908 0.499 25.657 0.470 2004 8 22.944 -0.953 0 0 22.853 -1.045 23.788 -0.887 2004 9 20.167 -0.280 0 0 20.075 -0.372 21.735 0.510 2004 10 14.944 0.970 0 0 14.853 0.879 16.029 1.278 2004 11 11.167 2.438 0 0 11.075 2.346 12.125 2.619 2004 12 4.611 0.708 0 1 4.707 0.804 5.087 0.407 2005 1 5.056 2.445 0 0 5.152 2.541 5.415 2.028 2005 2 5.833 1.887 0 0 5.929 1.983 5.712 0.988 2005 3 7.111 -1.356 0 0 7.207 -1.260 8.163 -1.082 2005 4 13.722 -0.255 0 0 13.818 -0.159 15.148 0.393 2005 5 16.611 -1.901 0 0 16.707 -1.805 17.779 -1.510 2005 6 21.944 -0.328 0 0 22.040 -0.232 23.358 0.308 2005 7 26.278 1.868 0 0 26.374 1.964 26.831 1.644 2005 8 25.278 1.380 0 0 25.374 1.476 26.228 1.553 2005 9 23.056 2.608 0 0 23.152 2.704 23.829 2.605 2005 10 15.722 1.748 0 0 15.818 1.844 16.121 1.369 2005 11 10.111 1.382 0 0 10.207 1.478 11.359 1.853 2005 12 3.667 -0.237 0 0 3.763 -0.141 3.759 -0.921 2006 1 7.389 4.779 0 0 7.485 4.875 7.556 4.169 2006 2 3.444 -0.502 0 0 3.540 -0.406 4.726 0.002 2006 3 9.611 1.144 0 0 9.707 1.240 10.286 1.041 2006 4 15.778 1.801 0 0 15.874 1.897 17.207 2.452 2006 5 16.667 -1.845 0 0 16.763 -1.749 17.964 -1.325 2006 6 21.944 -0.328 0 0 22.040 -0.232 23.130 0.080 2006 7 24.611 0.201 0 0 24.707 0.297 25.847 0.660 2006 8 25.444 1.547 0 0 25.540 1.643 26.550 1.875 2006 9 NaN NaN NaN NaN NaN NaN 20.565 -0.660 2006 10 NaN NaN NaN NaN NaN NaN 13.745 -1.006 2006 11 NaN NaN NaN NaN NaN NaN 11.172 1.666 2006 12 NaN NaN NaN NaN NaN NaN 7.658 2.977 2007 1 NaN NaN NaN NaN NaN NaN 6.199 2.811 2007 2 NaN NaN NaN NaN NaN NaN 2.605 -2.118 2007 3 NaN NaN NaN NaN NaN NaN 12.137 2.892 2007 4 NaN NaN NaN NaN NaN NaN 14.850 0.096 2007 5 NaN NaN NaN NaN NaN NaN 19.456 0.166 2007 6 NaN NaN NaN NaN NaN NaN 23.704 0.654 2007 7 NaN NaN NaN NaN NaN NaN 24.797 -0.390 2007 8 NaN NaN NaN NaN NaN NaN 28.145 3.470
