% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 31687 % Primary Name: NORFOLK/CHESAPEAK % Record Type: TAVG % Country: United States % State: VA % Latitude: 36.90000 +/- 0.00050 % Longitude: -75.71700 +/- 0.00050 % Elevation (m): 23.00 +/- 0.05 % # of Months: 61 % % IDs: gsod - 723077-99999 % icao - KW39 % usaf - 723077 % % Sources: Global Summary of the Day % % Site Hash: e2a332371b745fd30561b3abec8bc202 % Raw Data Hash: 92bdb869d8a827635f37e8ca92281d95 % Adj Data Hash: 11a34b232c6967ea1a586a0004dde439 % % 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 1974 9 NaN NaN NaN NaN NaN NaN 23.047 0.054 1974 10 NaN NaN NaN NaN NaN NaN 15.404 -2.239 1974 11 NaN NaN NaN NaN NaN NaN 12.939 0.087 1974 12 NaN NaN NaN NaN NaN NaN 9.013 0.788 1975 1 NaN NaN NaN NaN NaN NaN 8.954 2.670 1975 2 NaN NaN NaN NaN NaN NaN 8.054 1.530 1975 3 NaN NaN NaN NaN NaN NaN 9.861 0.155 1975 4 NaN NaN NaN NaN NaN NaN 12.049 -2.159 1975 5 NaN NaN NaN NaN NaN NaN 18.849 0.214 1975 6 NaN NaN NaN NaN NaN NaN 23.399 0.606 1975 7 NaN NaN NaN NaN NaN NaN 24.764 -0.528 1975 8 NaN NaN NaN NaN NaN NaN 26.545 1.217 1975 9 22.113 0.258 1 0 NaN NaN 23.458 0.464 1975 10 18.363 1.858 0 0 18.363 1.858 19.046 1.403 1975 11 14.172 2.458 0 0 14.172 2.458 15.235 2.382 1975 12 7.733 0.647 0 0 7.733 0.647 8.498 0.273 1976 1 4.396 -0.750 0 0 4.396 -0.750 5.511 -0.774 1976 2 8.685 3.299 0 0 8.685 3.299 10.046 3.522 1976 3 10.504 1.936 0 0 10.504 1.936 12.614 2.908 1976 4 13.556 0.485 0 0 13.556 0.485 15.604 1.395 1976 5 16.428 -1.068 0 0 16.428 -1.068 17.955 -0.680 1976 6 20.913 -0.741 0 0 20.913 -0.741 22.337 -0.455 1976 7 23.871 -0.283 0 0 23.871 -0.283 24.840 -0.452 1976 8 23.661 -0.528 0 0 23.661 -0.528 24.039 -1.289 1976 9 22.026 0.171 0 0 22.026 0.171 22.403 -0.591 1976 10 15.616 -0.888 0 0 15.616 -0.888 15.525 -2.118 1976 11 8.678 -3.036 0 0 8.678 -3.036 9.415 -3.437 1976 12 4.996 -2.090 0 0 4.996 -2.090 6.221 -2.004 1977 1 -0.746 -5.892 0 0 -0.746 -5.892 0.281 -6.004 1977 2 4.012 -1.374 0 0 4.012 -1.374 5.710 -0.814 1977 3 9.832 1.264 0 0 9.832 1.264 11.978 2.272 1977 4 14.189 1.119 0 0 14.189 1.119 16.413 2.205 1977 5 17.767 0.270 0 0 17.767 0.270 19.220 0.585 1977 6 21.230 -0.425 0 0 21.230 -0.425 22.235 -0.558 1977 7 25.375 1.221 0 0 25.375 1.221 26.390 1.098 1977 8 24.728 0.538 0 0 24.728 0.538 26.278 0.951 1977 9 23.481 1.626 0 0 23.481 1.626 24.912 1.918 1977 10 16.477 -0.028 0 0 16.477 -0.028 16.546 -1.097 1977 11 12.994 1.281 0 0 12.994 1.281 14.717 1.865 1977 12 7.342 0.256 0 0 7.342 0.256 8.081 -0.143 1978 1 3.224 -1.922 0 0 3.224 -1.922 4.059 -2.225 1978 2 0.550 -4.836 0 0 0.550 -4.836 0.784 -5.741 1978 3 6.409 -2.159 0 0 6.409 -2.159 8.305 -1.401 1978 4 11.982 -1.088 0 0 11.982 -1.088 14.409 0.200 1978 5 15.211 -2.286 0 0 15.211 -2.286 17.262 -1.373 1978 6 21.676 0.022 0 0 21.676 0.022 22.576 -0.217 1978 7 24.122 -0.032 0 0 24.122 -0.032 24.645 -0.648 1978 8 25.916 1.726 0 0 25.916 1.726 26.613 1.285 1978 9 22.752 0.897 1 0 NaN NaN 23.831 0.838 1978 10 17.120 0.615 0 0 17.120 0.615 16.977 -0.666 1978 11 14.327 2.613 1 0 NaN NaN 15.685 2.833 1978 12 8.329 1.243 1 0 NaN NaN 9.721 1.496 1979 1 5.651 0.504 0 0 5.651 0.504 6.132 -0.153 1979 2 1.131 -4.255 0 0 1.131 -4.255 2.281 -4.243 1979 3 7.803 -0.765 0 0 7.803 -0.765 10.183 0.477 1979 4 12.544 -0.526 0 0 12.544 -0.526 14.891 0.683 1979 5 17.133 -0.364 0 0 17.133 -0.364 18.617 -0.018 1979 6 20.776 -0.878 0 0 20.776 -0.878 20.993 -1.800 1979 7 24.556 0.402 0 0 24.556 0.402 24.700 -0.593 1979 8 25.151 0.961 0 0 25.151 0.961 25.664 0.336 1979 9 22.346 0.491 0 0 22.346 0.491 23.824 0.831 1979 10 17.170 0.665 0 0 17.170 0.665 17.369 -0.274 1979 11 14.272 2.558 0 0 14.272 2.558 15.181 2.329 1979 12 8.453 1.367 0 0 8.453 1.367 8.786 0.561 1980 1 5.506 0.359 0 0 5.506 0.359 6.316 0.032 1980 2 2.137 -3.249 0 0 2.137 -3.249 2.743 -3.782 1980 3 6.513 -2.055 0 0 6.513 -2.055 8.834 -0.872 1980 4 12.841 -0.230 0 0 12.841 -0.230 15.220 1.011 1980 5 18.054 0.557 0 0 18.054 0.557 19.052 0.417 1980 6 21.537 -0.117 0 0 21.537 -0.117 22.362 -0.431 1980 7 24.622 0.468 0 0 24.622 0.468 25.930 0.638 1980 8 24.489 0.300 0 0 24.489 0.300 26.414 1.086 1980 9 24.159 2.304 0 0 24.159 2.304 25.047 2.054 1980 10 NaN NaN NaN NaN NaN NaN 16.746 -0.897 1980 11 NaN NaN NaN NaN NaN NaN 11.954 -0.898 1980 12 NaN NaN NaN NaN NaN NaN 7.719 -0.506 1981 1 NaN NaN NaN NaN NaN NaN 2.384 -3.901 1981 2 NaN NaN NaN NaN NaN NaN 6.954 0.430 1981 3 NaN NaN NaN NaN NaN NaN 7.960 -1.746 1981 4 NaN NaN NaN NaN NaN NaN 16.268 2.060 1981 5 NaN NaN NaN NaN NaN NaN 17.442 -1.193 1981 6 NaN NaN NaN NaN NaN NaN 24.943 2.150 1981 7 NaN NaN NaN NaN NaN NaN 25.807 0.515 1981 8 NaN NaN NaN NaN NaN NaN 24.104 -1.223 1981 9 NaN NaN NaN NaN NaN NaN 22.350 -0.644
