% This file contains a station summary listing for a temperature % station in the Berkeley Earth database.

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 2006 7 NaN NaN NaN NaN NaN NaN 25.847 0.660 2006 8 NaN NaN NaN NaN NaN NaN 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 26.056 0.335 0 0 25.794 0.074 24.797 -0.390 2007 8 29.333 4.125 0 0 29.072 3.864 28.145 3.470 2007 9 NaN NaN NaN NaN NaN NaN 23.326 2.101 2007 10 20.150 4.865 1 0 NaN NaN 18.143 3.392 2007 11 NaN NaN NaN NaN NaN NaN 10.196 0.690 2007 12 9.889 4.675 0 0 9.628 4.414 7.754 3.073 2008 1 4.778 0.857 0 0 4.517 0.596 3.715 0.328 2008 2 8.650 3.393 1 0 NaN NaN 6.565 1.841 2008 3 11.111 1.333 0 0 10.850 1.072 10.486 1.241 2008 4 16.000 0.712 0 0 15.739 0.451 15.003 0.248 2008 5 19.278 -0.545 0 0 19.017 -0.806 18.446 -0.843 2008 6 27.000 3.417 0 0 26.739 3.155 25.522 2.472 2008 7 26.389 0.668 0 0 26.128 0.407 25.287 0.100 2008 8 25.472 0.263 1 0 NaN NaN 24.509 -0.166 2008 9 22.167 0.409 0 0 21.906 0.148 21.873 0.649 2008 10 15.135 -0.150 1 0 NaN NaN 13.952 -0.800 2008 11 9.333 -0.706 0 0 9.072 -0.967 8.842 -0.665 2008 12 7.111 1.897 0 0 6.850 1.636 6.644 1.963 2009 1 4.389 0.468 0 0 4.128 0.207 2.765 -0.623 2009 2 5.633 0.376 1 0 NaN NaN 5.508 0.785 2009 3 10.911 1.133 1 0 NaN NaN 9.421 0.177 2009 4 16.301 1.014 1 0 NaN NaN 15.701 0.946 2009 5 21.500 1.677 0 0 21.239 1.416 19.921 0.631 2009 6 25.222 1.639 0 0 24.961 1.378 24.090 1.040 2009 7 25.500 -0.220 0 0 25.239 -0.482 24.513 -0.675 2009 8 26.833 1.625 0 0 26.572 1.364 25.912 1.237 2009 9 21.833 0.075 0 0 21.572 -0.186 21.305 0.080 2009 10 15.611 0.326 1 0 NaN NaN 14.386 -0.365 2009 11 11.778 1.738 0 0 11.517 1.477 11.648 2.142 2009 12 4.638 -0.576 1 0 NaN NaN 3.673 -1.008 2010 1 2.605 -1.316 1 0 NaN NaN 1.975 -1.413 2010 2 2.703 -2.554 1 0 NaN NaN 1.714 -3.009 2010 3 9.797 0.019 1 0 NaN NaN 10.326 1.082 2010 4 17.177 1.889 1 0 NaN NaN 17.177 2.423 2010 5 22.141 2.318 1 0 NaN NaN 21.150 1.860 2010 6 27.278 3.694 0 0 27.017 3.433 26.201 3.151 2010 7 27.667 1.946 0 1 27.841 2.120 26.791 1.604 2010 8 27.778 2.569 0 0 27.952 2.743 26.367 1.692 2010 9 25.167 3.409 0 0 25.341 3.583 23.638 2.413 2010 10 17.833 2.548 0 0 18.007 2.723 15.943 1.192 2010 11 10.772 0.733 1 0 NaN NaN 10.109 0.602 2010 12 -0.444 -5.659 0 0 -0.270 -5.485 0.726 -3.955 2011 1 1.778 -2.143 0 0 1.952 -1.969 1.944 -1.444 2011 2 4.333 -0.923 0 0 4.507 -0.749 6.566 1.843 2011 3 6.500 -3.278 0 0 6.674 -3.104 10.113 0.869 2011 4 15.284 -0.003 1 0 NaN NaN 16.988 2.234 2011 5 17.556 -2.267 0 0 17.730 -2.093 20.007 0.717 2011 6 21.914 -1.669 0 0 22.089 -1.495 25.244 2.194 2011 7 18.889 -6.832 1 0 NaN NaN 27.300 2.113 2011 8 18.000 -7.208 1 0 NaN NaN 26.086 1.411 2011 9 NaN NaN NaN NaN NaN NaN 22.266 1.042 2011 10 NaN NaN NaN NaN NaN NaN 14.222 -0.529 2011 11 10.667 0.627 0 0 10.841 0.801 11.690 2.184 2011 12 8.680 3.466 0 0 8.854 3.640 7.666 2.986 2012 1 7.125 3.204 0 0 7.299 3.378 5.752 2.364 2012 2 8.021 2.764 0 0 8.195 2.938 6.576 1.852 2012 3 15.748 5.970 0 0 15.922 6.144 14.787 5.542 2012 4 16.037 0.749 1 0 NaN NaN 15.395 0.641 2012 5 21.924 2.101 0 0 22.098 2.275 21.288 1.999 2012 6 23.903 0.319 1 0 NaN NaN 22.785 -0.266 2012 7 28.969 3.249 0 0 29.143 3.423 27.425 2.238 2012 8 25.863 0.655 0 0 26.037 0.829 24.833 0.158 2012 9 21.684 -0.074 0 0 21.858 0.100 21.376 0.151 2012 10 15.554 0.269 1 0 NaN NaN 14.791 0.039 2012 11 7.666 -2.374 0 0 7.840 -2.199 8.173 -1.334 2012 12 9.041 3.827 0 0 9.215 4.001 8.069 3.388 2013 1 6.331 2.410 0 0 6.505 2.584 5.697 2.309 2013 2 5.325 0.068 0 0 5.499 0.242 4.141 -0.583 2013 3 7.185 -2.593 0 0 7.359 -2.419 6.572 -2.673 2013 4 15.869 0.581 0 0 16.043 0.755 15.667 0.912 2013 5 20.019 0.196 0 0 20.193 0.370 18.476 -0.814 2013 6 23.959 0.375 0 0 24.133 0.549 23.701 0.651 2013 7 26.069 0.349 0 0 26.243 0.523 25.472 0.285 2013 8 24.677 -0.532 0 0 24.851 -0.357 23.881 -0.794 2013 9 21.677 -0.081 0 0 21.851 0.093 21.242 0.018 2013 10 NaN NaN NaN NaN NaN NaN 15.716 0.964
