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 2010 1 NaN NaN NaN NaN NaN NaN -1.311 0.125 2010 2 NaN NaN NaN NaN NaN NaN 0.357 0.533 2010 3 NaN NaN NaN NaN NaN NaN 6.081 3.064 2010 4 NaN NaN NaN NaN NaN NaN 11.136 3.713 2010 5 NaN NaN NaN NaN NaN NaN 13.636 1.723 2010 6 NaN NaN NaN NaN NaN NaN 18.992 1.394 2010 7 NaN NaN NaN NaN NaN NaN 23.726 2.002 2010 8 NaN NaN NaN NaN NaN NaN 24.518 2.250 2010 9 NaN NaN NaN NaN NaN NaN 19.086 0.280 2010 10 NaN NaN NaN NaN NaN NaN 14.947 1.805 2010 11 NaN NaN NaN NaN NaN NaN 8.750 1.778 2010 12 NaN NaN NaN NaN NaN NaN -0.322 -1.731 2011 1 -5.778 -3.477 0 0 -5.778 -3.477 -2.325 -0.888 2011 2 NaN NaN NaN NaN NaN NaN -0.132 0.044 2011 3 2.167 0.013 0 0 2.167 0.013 3.070 0.053 2011 4 8.222 1.664 0 0 8.222 1.664 7.600 0.178 2011 5 15.333 4.284 0 0 15.333 4.284 11.991 0.077 2011 6 20.889 4.155 0 0 20.889 4.155 17.987 0.389 2011 7 24.778 3.918 0 0 24.778 3.918 24.045 2.321 2011 8 22.278 0.874 0 0 22.278 0.874 23.029 0.761 2011 9 16.222 -1.720 0 0 16.222 -1.720 18.206 -0.600 2011 10 12.111 -0.167 0 0 12.111 -0.167 14.223 1.081 2011 11 5.444 -0.662 0 0 5.444 -0.662 9.779 2.808 2011 12 0.285 -0.259 0 0 0.285 -0.259 5.104 3.695 2012 1 -2.213 0.088 0 0 -2.213 0.088 1.965 3.401 2012 2 -0.276 0.765 0 0 -0.276 0.765 3.305 3.482 2012 3 10.553 8.400 0 0 10.553 8.400 11.816 8.799 2012 4 9.513 2.955 0 0 9.513 2.955 8.639 1.216 2012 5 17.855 6.805 0 0 17.855 6.805 14.828 2.914 2012 6 21.765 5.031 0 0 21.765 5.031 19.746 2.147 2012 7 26.711 5.851 0 0 26.711 5.851 25.577 3.852 2012 8 22.106 0.702 1 0 NaN NaN 22.619 0.350 2012 9 17.203 -0.739 1 0 NaN NaN 18.757 -0.049 2012 10 10.239 -2.039 0 0 10.239 -2.039 12.804 -0.339 2012 11 3.720 -2.387 0 0 3.720 -2.387 7.641 0.670 2012 12 1.140 0.596 0 0 1.140 0.596 5.431 4.023 2013 1 -3.911 -1.611 0 0 -3.911 -1.611 0.493 1.929 2013 2 -4.005 -2.965 1 0 NaN NaN -0.749 -0.573 2013 3 -0.418 -2.571 0 0 -0.418 -2.571 1.105 -1.913 2013 4 7.472 0.914 0 0 7.472 0.914 6.933 -0.489 2013 5 16.211 5.162 0 0 16.211 5.162 13.236 1.323 2013 6 19.860 3.126 0 0 19.860 3.126 17.566 -0.032 2013 7 22.208 1.348 0 0 22.208 1.348 21.612 -0.112 2013 8 21.866 0.462 0 0 21.866 0.462 22.200 -0.069 2013 9 18.064 0.122 0 0 18.064 0.122 19.771 0.965 2013 10 NaN NaN NaN NaN NaN NaN 13.813 0.671
