% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 29632 % Primary Name: COURTLAND AIRPORT % Record Type: TAVG % Country: United States % State: AL % Latitude: 34.65900 +/- 0.00050 % Longitude: -87.34900 +/- 0.00050 % Elevation (m): 179.00 +/- 0.05 % # of Months: 32 % % IDs: gsod - 720773-99999 % icao - K9A4 % usaf - 720773 % % Sources: Global Summary of the Day % % Site Hash: 149508eeed1e42d4fd9be41cdd5e7db6 % Raw Data Hash: 402b39d9cdcb66215469ee6aebac72db % Adj Data Hash: 40095554ea03a6c8c230c46f5e220988 % % 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 10 NaN NaN NaN NaN NaN NaN 15.062 -0.772 2009 11 NaN NaN NaN NaN NaN NaN 11.496 1.450 2009 12 NaN NaN NaN NaN NaN NaN 5.120 -0.731 2010 1 NaN NaN NaN NaN NaN NaN 1.473 -2.653 2010 2 NaN NaN NaN NaN NaN NaN 2.245 -3.882 2010 3 NaN NaN NaN NaN NaN NaN 9.506 -1.023 2010 4 NaN NaN NaN NaN NaN NaN 17.709 1.660 2010 5 NaN NaN NaN NaN NaN NaN 21.864 1.495 2010 6 NaN NaN NaN NaN NaN NaN 27.258 2.891 2010 7 NaN NaN NaN NaN NaN NaN 28.093 1.894 2010 8 NaN NaN NaN NaN NaN NaN 28.484 2.758 2010 9 NaN NaN NaN NaN NaN NaN 24.444 1.921 2010 10 18.815 3.769 1 0 NaN NaN 16.687 0.853 2010 11 11.588 2.330 1 0 NaN NaN 11.519 1.473 2010 12 4.839 -0.224 1 0 NaN NaN 2.998 -2.853 2011 1 2.578 -0.761 0 0 2.578 -0.761 2.270 -1.857 2011 2 8.242 2.902 0 0 8.242 2.902 7.533 1.406 2011 3 11.389 1.648 0 0 11.389 1.648 11.913 1.384 2011 4 17.560 2.300 0 0 17.560 2.300 18.093 2.044 2011 5 20.081 0.500 0 0 20.081 0.500 20.273 -0.096 2011 6 26.211 2.632 0 0 26.211 2.632 27.015 2.648 2011 7 26.686 1.275 0 0 26.686 1.275 27.984 1.785 2011 8 25.599 0.660 0 0 25.599 0.660 27.143 1.417 2011 9 19.950 -1.786 0 0 19.950 -1.786 21.628 -0.896 2011 10 14.936 -0.110 1 0 NaN NaN 14.785 -1.048 2011 11 11.492 2.234 1 0 NaN NaN 12.134 2.088 2011 12 7.848 2.785 1 0 NaN NaN 7.513 1.662 2012 1 NaN NaN NaN NaN NaN NaN 7.485 3.359 2012 2 NaN NaN NaN NaN NaN NaN 8.342 2.215 2012 3 16.646 6.905 0 0 16.646 6.905 16.932 6.403 2012 4 16.086 0.826 0 0 16.086 0.826 17.648 1.600 2012 5 23.304 3.723 1 0 NaN NaN 22.468 2.099 2012 6 23.936 0.357 0 0 23.936 0.357 25.061 0.694 2012 7 26.276 0.865 0 0 26.276 0.865 28.004 1.805 2012 8 24.052 -0.886 0 0 24.052 -0.886 25.532 -0.194 2012 9 23.863 2.127 1 0 NaN NaN 22.491 -0.032 2012 10 15.368 0.323 0 0 15.368 0.323 15.221 -0.613 2012 11 7.504 -1.754 0 0 7.504 -1.754 9.414 -0.632 2012 12 7.921 2.858 0 0 7.921 2.858 9.201 3.350 2013 1 6.606 3.267 0 0 6.606 3.267 6.545 2.418 2013 2 6.315 0.976 0 0 6.315 0.976 6.232 0.104 2013 3 7.618 -2.122 0 0 7.618 -2.122 7.819 -2.710 2013 4 14.459 -0.801 0 0 14.459 -0.801 15.839 -0.209 2013 5 18.744 -0.837 0 0 18.744 -0.837 19.568 -0.801 2013 6 24.385 0.806 0 0 24.385 0.806 25.322 0.955 2013 7 24.262 -1.149 0 0 24.262 -1.149 25.198 -1.001 2013 8 NaN NaN NaN NaN NaN NaN 25.273 -0.454 2013 9 NaN NaN NaN NaN NaN NaN 23.732 1.208 2013 10 NaN NaN NaN NaN NaN NaN 16.891 1.057
