% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 32797 % Primary Name: COLUMBIA % Record Type: TAVG % Country: United States % State: CA % Latitude: 38.03300 +/- 0.00050 % Longitude: -120.41700 +/- 0.00050 % Elevation (m): 646.00 +/- 0.05 % # of Months: 55 % % IDs: gsod - 720615-99999 % icao - KO22 % usaf - 720615 % % Sources: Global Summary of the Day % % Site Hash: 93a179fd34da5519240d70c6f6580ccd % Raw Data Hash: a75061290d29e304a2ef1c0244aa4747 % Adj Data Hash: 6fab3cbcea423037e4d56f35b320c924 % % 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 2008 1 NaN NaN NaN NaN NaN NaN 3.057 -0.557 2008 2 NaN NaN NaN NaN NaN NaN 6.008 0.360 2008 3 NaN NaN NaN NaN NaN NaN 7.802 0.673 2008 4 NaN NaN NaN NaN NaN NaN 10.057 0.237 2008 5 NaN NaN NaN NaN NaN NaN 14.918 0.740 2008 6 NaN NaN NaN NaN NaN NaN 19.759 1.218 2008 7 NaN NaN NaN NaN NaN NaN 23.910 1.565 2008 8 NaN NaN NaN NaN NaN NaN 23.209 1.664 2008 9 NaN NaN NaN NaN NaN NaN 20.651 1.896 2008 10 NaN NaN NaN NaN NaN NaN 15.087 1.431 2008 11 NaN NaN NaN NaN NaN NaN 10.057 2.192 2008 12 NaN NaN NaN NaN NaN NaN 3.453 -0.579 2009 1 7.642 2.985 1 0 NaN NaN 6.010 2.396 2009 2 6.687 -0.005 0 0 6.687 -0.005 5.721 0.073 2009 3 8.502 0.330 0 0 8.502 0.330 6.847 -0.281 2009 4 11.315 0.451 0 0 11.315 0.451 9.765 -0.056 2009 5 18.627 3.406 0 0 18.627 3.406 17.505 3.327 2009 6 19.561 -0.023 0 0 19.561 -0.023 17.412 -1.129 2009 7 25.348 1.959 0 0 25.348 1.959 24.143 1.798 2009 8 23.685 1.096 0 0 23.685 1.096 21.853 0.308 2009 9 22.202 2.404 0 0 22.202 2.404 21.509 2.754 2009 10 12.948 -1.751 0 0 12.948 -1.751 12.707 -0.950 2009 11 8.504 -0.405 0 0 8.504 -0.405 8.630 0.765 2009 12 4.728 -0.348 0 0 4.728 -0.348 3.370 -0.663 2010 1 6.789 2.132 0 0 6.789 2.132 5.136 1.522 2010 2 7.720 1.028 1 0 NaN NaN 6.443 0.795 2010 3 8.441 0.269 0 0 8.441 0.269 6.808 -0.321 2010 4 8.937 -1.927 0 0 8.937 -1.927 7.386 -2.435 2010 5 12.349 -2.872 0 0 12.349 -2.872 11.195 -2.982 2010 6 20.106 0.522 0 0 20.106 0.522 18.589 0.049 2010 7 24.505 1.117 0 0 24.505 1.117 23.363 1.018 2010 8 22.285 -0.303 0 0 22.285 -0.303 20.915 -0.630 2010 9 20.220 0.422 0 0 20.220 0.422 19.972 1.217 2010 10 15.140 0.440 0 0 15.140 0.440 14.412 0.756 2010 11 7.600 -1.308 1 0 NaN NaN 7.065 -0.800 2010 12 7.018 1.942 0 0 7.018 1.942 5.403 1.370 2011 1 5.219 0.561 0 0 5.219 0.561 5.032 1.418 2011 2 4.978 -1.713 0 0 4.978 -1.713 4.496 -1.152 2011 3 7.747 -0.424 0 0 7.747 -0.424 6.329 -0.800 2011 4 10.652 -0.212 0 0 10.652 -0.212 9.118 -0.703 2011 5 12.532 -2.689 0 0 12.532 -2.689 11.704 -2.474 2011 6 18.365 -1.219 0 0 18.365 -1.219 16.870 -1.671 2011 7 23.203 -0.186 0 0 23.203 -0.186 22.107 -0.238 2011 8 23.550 0.962 0 0 23.550 0.962 22.017 0.472 2011 9 22.248 2.450 1 0 NaN NaN 21.358 2.603 2011 10 14.667 -0.033 0 0 14.667 -0.033 14.826 1.170 2011 11 7.731 -1.177 1 0 NaN NaN 7.279 -0.587 2011 12 4.242 -0.834 0 0 4.242 -0.834 4.150 0.118 2012 1 6.140 1.483 0 0 6.140 1.483 6.356 2.742 2012 2 6.736 0.044 0 0 6.736 0.044 6.281 0.632 2012 3 8.113 -0.059 0 0 8.113 -0.059 7.009 -0.120 2012 4 11.667 0.803 0 0 11.667 0.803 10.569 0.749 2012 5 16.470 1.248 0 0 16.470 1.248 15.692 1.514 2012 6 20.019 0.435 0 0 20.019 0.435 18.700 0.159 2012 7 23.869 0.481 0 0 23.869 0.481 22.986 0.641 2012 8 25.849 3.261 0 0 25.849 3.261 24.144 2.598 2012 9 22.263 2.465 1 0 NaN NaN 21.760 3.005 2012 10 15.005 0.306 0 0 15.005 0.306 15.230 1.573 2012 11 9.781 0.873 0 0 9.781 0.873 9.169 1.304 2012 12 5.805 0.729 0 0 5.805 0.729 3.756 -0.276 2013 1 4.378 -0.279 0 0 4.378 -0.279 3.456 -0.158 2013 2 5.476 -1.215 0 0 5.476 -1.215 5.451 -0.197 2013 3 10.769 2.597 0 0 10.769 2.597 9.668 2.539 2013 4 13.778 2.914 0 0 13.778 2.914 12.242 2.422 2013 5 17.091 1.870 0 0 17.091 1.870 15.656 1.478 2013 6 21.969 2.385 0 0 21.969 2.385 20.439 1.899 2013 7 25.978 2.590 0 0 25.978 2.590 24.733 2.388 2013 8 NaN NaN NaN NaN NaN NaN 21.666 0.121 2013 9 NaN NaN NaN NaN NaN NaN 19.117 0.362 2013 10 NaN NaN NaN NaN NaN NaN 13.324 -0.332
