% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 32170 % Primary Name: CHESTERFIELD AIRPORT % Record Type: TAVG % Country: United States % State: VA % Latitude: 37.40000 +/- 0.00050 % Longitude: -77.51700 +/- 0.00050 % Elevation (m): 72.00 +/- 0.05 % # of Months: 42 % % IDs: gsod - 720498-99999 % icao - KFCI % usaf - 720498 % % Sources: Global Summary of the Day % % Site Hash: 2887df60e4cf252323ac6b888fb8b221 % Raw Data Hash: 5e51cffe84f7629f9ae5d76c6610a9e4 % Adj Data Hash: 6f64124dbb607c14f4b4200647c776da % % The data for this station is presented below in several columns and in % several forms. 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 2009 5 NaN NaN NaN NaN NaN NaN 19.238 0.542 2009 6 NaN NaN NaN NaN NaN NaN 23.300 0.372 2009 7 NaN NaN NaN NaN NaN NaN 24.291 -0.981 2009 8 NaN NaN NaN NaN NaN NaN 26.046 1.383 2009 9 NaN NaN NaN NaN NaN NaN 20.752 -0.273 2009 10 NaN NaN NaN NaN NaN NaN 14.108 -0.290 2009 11 NaN NaN NaN NaN NaN NaN 11.323 2.367 2009 12 NaN NaN NaN NaN NaN NaN 3.000 -0.733 2010 1 NaN NaN NaN NaN NaN NaN 1.278 -0.743 2010 2 NaN NaN NaN NaN NaN NaN 0.551 -2.778 2010 3 NaN NaN NaN NaN NaN NaN 10.210 2.098 2010 4 NaN NaN NaN NaN NaN NaN 16.471 2.669 2010 5 21.622 2.848 1 0 NaN NaN 20.338 1.642 2010 6 27.663 4.656 0 0 27.663 4.656 26.055 3.127 2010 7 NaN NaN NaN NaN NaN NaN 27.397 2.125 2010 8 26.787 2.046 1 0 NaN NaN 26.076 1.413 2010 9 23.019 1.914 0 0 23.019 1.914 23.316 2.291 2010 10 15.600 1.124 0 0 15.600 1.124 15.463 1.065 2010 11 8.528 -0.506 0 0 8.528 -0.506 9.589 0.633 2010 12 0.068 -3.744 0 0 0.068 -3.744 0.109 -3.624 2011 1 1.061 -1.039 0 0 1.061 -1.039 0.559 -1.462 2011 2 6.629 3.221 0 0 6.629 3.221 5.390 2.061 2011 3 9.306 1.117 0 0 9.306 1.117 8.813 0.702 2011 4 16.369 2.488 0 0 16.369 2.488 16.387 2.585 2011 5 20.106 1.331 1 0 NaN NaN 19.810 1.114 2011 6 24.558 1.551 0 0 24.558 1.551 24.521 1.593 2011 7 26.995 1.644 0 0 26.995 1.644 27.080 1.809 2011 8 25.731 0.990 0 0 25.731 0.990 25.429 0.766 2011 9 23.025 1.920 1 0 NaN NaN 22.157 1.132 2011 10 12.867 -1.609 1 0 NaN NaN 14.221 -0.177 2011 11 11.255 2.221 0 0 11.255 2.221 11.484 2.529 2011 12 7.544 3.732 0 0 7.544 3.732 6.920 3.187 2012 1 7.140 5.040 1 0 NaN NaN 4.768 2.747 2012 2 6.739 3.332 0 0 6.739 3.332 5.863 2.534 2012 3 14.482 6.292 0 0 14.482 6.292 13.946 5.835 2012 4 14.330 0.449 0 0 14.330 0.449 14.552 0.751 2012 5 20.729 1.955 0 0 20.729 1.955 20.726 2.030 2012 6 22.946 -0.060 0 0 22.946 -0.060 22.740 -0.187 2012 7 27.828 2.478 0 0 27.828 2.478 27.631 2.359 2012 8 24.884 0.142 0 0 24.884 0.142 25.276 0.614 2012 9 20.546 -0.558 0 0 20.546 -0.558 21.158 0.133 2012 10 14.661 0.184 0 0 14.661 0.184 14.819 0.421 2012 11 4.506 -4.529 0 0 4.506 -4.529 7.458 -1.498 2012 12 7.183 3.371 0 0 7.183 3.371 6.864 3.131 2013 1 4.738 2.639 0 0 4.738 2.639 4.060 2.039 2013 2 3.951 0.543 0 0 3.951 0.543 3.067 -0.262 2013 3 5.625 -2.564 0 0 5.625 -2.564 5.806 -2.306 2013 4 15.163 1.283 0 0 15.163 1.283 15.046 1.245 2013 5 18.427 -0.348 0 0 18.427 -0.348 18.371 -0.325 2013 6 23.620 0.614 0 0 23.620 0.614 23.653 0.725 2013 7 25.448 0.098 0 0 25.448 0.098 26.022 0.751 2013 8 23.056 -1.686 0 0 23.056 -1.686 23.601 -1.061 2013 9 21.009 -0.095 0 0 21.009 -0.095 20.498 -0.527 2013 10 16.156 1.679 0 0 16.156 1.679 15.326 0.928 2013 11 12.333 3.299 1 0 NaN NaN NaN NaN
