% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 37224 % Primary Name: CHICAGO/CALUMET CGS % Record Type: TAVG % Country: United States % State: IL % Latitude: 41.71700 +/- 0.00050 % Longitude: -87.53300 +/- 0.00050 % Elevation (m): 180.00 +/- 0.05 % # of Months: 28 % % IDs: gsod - 725344-99999 % icao - K63G % usaf - 725344 % % Sources: Global Summary of the Day % % Site Hash: fcf43631758a1765170ed69ccae23e3c % Raw Data Hash: 931fd585ebc9a5de434351552fbd0963 % Adj Data Hash: cbff8950b8cd827baf4af5c45cc159e3 % % 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 1993 3 NaN NaN NaN NaN NaN NaN 1.808 -1.214 1993 4 NaN NaN NaN NaN NaN NaN 9.211 -0.840 1993 5 NaN NaN NaN NaN NaN NaN 16.998 0.901 1993 6 NaN NaN NaN NaN NaN NaN 21.148 -0.264 1993 7 NaN NaN NaN NaN NaN NaN 24.146 0.744 1993 8 NaN NaN NaN NaN NaN NaN 23.194 0.914 1993 9 NaN NaN NaN NaN NaN NaN 16.284 -2.293 1993 10 NaN NaN NaN NaN NaN NaN 10.930 -1.065 1993 11 NaN NaN NaN NaN NaN NaN 4.634 0.031 1993 12 NaN NaN NaN NaN NaN NaN -1.240 0.676 1994 1 NaN NaN NaN NaN NaN NaN -8.666 -3.493 1994 2 NaN NaN NaN NaN NaN NaN -4.836 -2.131 1994 3 4.158 1.415 0 0 4.158 1.415 3.591 0.570 1994 4 10.647 0.874 0 0 10.647 0.874 11.455 1.404 1994 5 13.071 -2.748 0 0 13.071 -2.748 15.000 -1.097 1994 6 19.447 -1.686 0 0 19.447 -1.686 22.827 1.416 1994 7 22.220 -0.903 0 0 22.220 -0.903 22.845 -0.557 1994 8 20.599 -1.402 0 0 20.599 -1.402 20.585 -1.695 1994 9 19.486 1.187 0 0 19.486 1.187 18.871 0.293 1994 10 13.206 1.489 0 0 13.206 1.489 13.268 1.272 1994 11 8.513 4.188 0 0 8.513 4.188 7.833 3.230 1994 12 2.224 4.419 1 0 NaN NaN 2.042 3.958 1995 1 -4.202 1.249 0 0 -4.202 1.249 -4.694 0.478 1995 2 -5.259 -2.276 1 0 NaN NaN -2.615 0.091 1995 3 -0.477 -3.220 1 0 NaN NaN 5.266 2.244 1995 4 7.935 -1.837 1 0 NaN NaN 9.172 -0.879 1995 5 14.387 -1.432 1 0 NaN NaN 15.101 -0.996 1995 6 21.913 0.780 1 0 NaN NaN 22.826 1.415 1995 7 24.964 1.840 0 0 24.964 1.840 24.705 1.303 1995 8 25.187 3.186 0 0 25.187 3.186 25.853 3.574 1995 9 18.362 0.064 0 0 18.362 0.064 17.809 -0.768 1995 10 13.101 1.384 1 0 NaN NaN 12.939 0.944 1995 11 1.244 -3.081 0 0 1.244 -3.081 1.628 -2.975 1995 12 -2.720 -0.526 0 0 -2.720 -0.526 -3.222 -1.306 1996 1 -3.430 2.021 0 0 -3.430 2.021 -5.463 -0.290 1996 2 -2.794 0.190 0 0 -2.794 0.190 -2.427 0.278 1996 3 -0.377 -3.120 0 0 -0.377 -3.120 0.292 -2.730 1996 4 6.589 -3.183 0 0 6.589 -3.183 8.704 -1.347 1996 5 12.544 -3.275 1 0 NaN NaN 14.905 -1.193 1996 6 18.670 -2.462 1 0 NaN NaN 21.822 0.410 1996 7 NaN NaN NaN NaN NaN NaN 21.988 -1.414 1996 8 NaN NaN NaN NaN NaN NaN 22.583 0.303 1996 9 NaN NaN NaN NaN NaN NaN 18.128 -0.449 1996 10 NaN NaN NaN NaN NaN NaN 12.631 0.635 1996 11 NaN NaN NaN NaN NaN NaN 1.604 -3.000 1996 12 NaN NaN NaN NaN NaN NaN -1.398 0.518 1997 1 NaN NaN NaN NaN NaN NaN -7.604 -2.431 1997 2 NaN NaN NaN NaN NaN NaN -0.600 2.105 1997 3 NaN NaN NaN NaN NaN NaN 4.731 1.710 1997 4 NaN NaN NaN NaN NaN NaN 8.225 -1.826 1997 5 NaN NaN NaN NaN NaN NaN 13.215 -2.882 1997 6 NaN NaN NaN NaN NaN NaN 21.509 0.098
