% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 31729 % Primary Name: SEWELLS POINT % Record Type: TAVG % Country: United States % State: VA % Latitude: 36.95000 +/- 0.00050 % Longitude: -76.33300 +/- 0.00050 % Elevation (m): 10.00 +/- 0.05 % # of Months: 12 % % IDs: gsod - 993711-99999 % icao - SWPV2 % usaf - 993711 % % Sources: Global Summary of the Day % % Site Hash: d8ee5e3e9a245109f8a90f070faa6009 % Raw Data Hash: dbd2fe70d563d60290895c93757c2b50 % Adj Data Hash: b892f3d1ab35b8065df88cc70ac5a95d % % 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 2004 2 NaN NaN NaN NaN NaN NaN 6.004 -0.520 2004 3 NaN NaN NaN NaN NaN NaN 10.699 0.993 2004 4 NaN NaN NaN NaN NaN NaN 15.193 0.984 2004 5 NaN NaN NaN NaN NaN NaN 22.048 3.413 2004 6 NaN NaN NaN NaN NaN NaN 23.802 1.009 2004 7 NaN NaN NaN NaN NaN NaN 26.378 1.085 2004 8 NaN NaN NaN NaN NaN NaN 24.822 -0.505 2004 9 NaN NaN NaN NaN NaN NaN 23.787 0.793 2004 10 NaN NaN NaN NaN NaN NaN 17.544 -0.100 2004 11 NaN NaN NaN NaN NaN NaN 14.104 1.252 2004 12 NaN NaN NaN NaN NaN NaN 8.960 0.735 2005 1 NaN NaN NaN NaN NaN NaN 7.023 0.738 2005 2 4.509 -1.484 1 0 NaN NaN 6.215 -0.309 2005 3 7.088 -2.088 0 0 7.088 -2.088 7.964 -1.742 2005 4 13.770 0.092 0 0 13.770 0.092 14.270 0.062 2005 5 16.690 -1.414 0 0 16.690 -1.414 16.319 -2.316 2005 6 23.541 1.279 0 0 23.541 1.279 23.015 0.222 2005 7 26.826 2.065 0 0 26.826 2.065 26.782 1.489 2005 8 27.075 2.278 1 0 NaN NaN 26.999 1.672 2005 9 25.068 2.605 1 0 NaN NaN 25.329 2.335 2005 10 18.344 1.232 0 0 18.344 1.232 18.825 1.182 2005 11 13.306 0.984 0 0 13.306 0.984 14.906 2.054 2005 12 5.866 -1.828 0 0 5.866 -1.828 7.596 -0.628 2006 1 8.643 2.889 1 0 NaN NaN 10.007 3.723 2006 2 NaN NaN NaN NaN NaN NaN 6.738 0.214 2006 3 NaN NaN NaN NaN NaN NaN 9.933 0.227 2006 4 NaN NaN NaN NaN NaN NaN 15.941 1.732 2006 5 NaN NaN NaN NaN NaN NaN 17.994 -0.641 2006 6 NaN NaN NaN NaN NaN NaN 22.956 0.163 2006 7 NaN NaN NaN NaN NaN NaN 26.378 1.086 2006 8 NaN NaN NaN NaN NaN NaN 26.832 1.505 2006 9 NaN NaN NaN NaN NaN NaN 22.370 -0.623 2006 10 NaN NaN NaN NaN NaN NaN 17.397 -0.246 2006 11 NaN NaN NaN NaN NaN NaN 14.645 1.792 2006 12 NaN NaN NaN NaN NaN NaN 11.194 2.969 2007 1 NaN NaN NaN NaN NaN NaN 9.413 3.129
