% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 39554 % Primary Name: SAGINAW BAY LIGHT 1 % Record Type: TAVG % Country: United States % State: MI % Latitude: 43.80000 +/- 0.00050 % Longitude: -83.71700 +/- 0.00050 % Elevation (m): 188.00 +/- 0.05 % # of Months: 61 % % IDs: gsod - 998242-99999 % icao - SBLM4 % usaf - 998242 % % Sources: Global Summary of the Day % % Site Hash: 01cce2be6e1899a1b63cdaa72e3bd810 % Raw Data Hash: 3c99ffbc8393aefc6d8f11ac20a75c0a % Adj Data Hash: 7170a335769a08a5eef87a65b64335b8 % % 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 2007 11 NaN NaN NaN NaN NaN NaN 4.388 0.213 2007 12 NaN NaN NaN NaN NaN NaN -2.080 0.070 2008 1 NaN NaN NaN NaN NaN NaN -2.850 2.627 2008 2 NaN NaN NaN NaN NaN NaN -5.999 -0.695 2008 3 NaN NaN NaN NaN NaN NaN -1.773 -0.713 2008 4 NaN NaN NaN NaN NaN NaN 8.131 2.987 2008 5 NaN NaN NaN NaN NaN NaN 9.164 -1.403 2008 6 NaN NaN NaN NaN NaN NaN 17.108 1.223 2008 7 NaN NaN NaN NaN NaN NaN 19.493 0.429 2008 8 NaN NaN NaN NaN NaN NaN 18.878 -0.055 2008 9 NaN NaN NaN NaN NaN NaN 16.376 0.989 2008 10 NaN NaN NaN NaN NaN NaN 9.814 -0.185 2008 11 0.781 -4.133 1 0 NaN NaN 4.827 0.652 2008 12 -4.271 -2.860 0 0 -4.271 -2.860 -3.667 -1.518 2009 1 -9.000 -4.262 0 0 -9.000 -4.262 -8.721 -3.244 2009 2 -3.982 0.583 0 0 -3.982 0.583 -3.925 1.379 2009 3 0.314 0.635 0 0 0.314 0.635 0.189 1.249 2009 4 6.100 0.217 0 0 6.100 0.217 6.162 1.018 2009 5 13.281 1.976 0 0 13.281 1.976 10.576 0.009 2009 6 17.487 0.864 0 0 17.487 0.864 14.413 -1.472 2009 7 19.283 -0.519 0 0 19.283 -0.519 17.029 -2.035 2009 8 20.373 0.702 0 0 20.373 0.702 18.801 -0.131 2009 9 17.972 1.847 0 0 17.972 1.847 16.250 0.864 2009 10 8.973 -1.764 0 0 8.973 -1.764 9.078 -0.920 2009 11 6.850 1.936 0 0 6.850 1.936 7.536 3.361 2009 12 -1.880 -0.469 0 0 -1.880 -0.469 -1.826 0.323 2010 1 -5.274 -0.536 1 0 NaN NaN -4.277 1.200 2010 2 -3.946 0.619 0 0 -3.946 0.619 -3.847 1.457 2010 3 2.127 2.449 0 0 2.127 2.449 2.978 4.039 2010 4 9.461 3.579 0 0 9.461 3.579 8.949 3.805 2010 5 15.226 3.920 0 0 15.226 3.920 12.996 2.429 2010 6 19.526 2.902 0 0 19.526 2.902 16.656 0.771 2010 7 23.622 3.820 0 0 23.622 3.820 21.121 2.057 2010 8 23.082 3.411 0 0 23.082 3.411 21.232 2.299 2010 9 16.380 0.254 0 0 16.380 0.254 15.590 0.203 2010 10 11.584 0.847 0 0 11.584 0.847 11.296 1.297 2010 11 4.872 -0.041 0 0 4.872 -0.041 5.640 1.465 2010 12 -3.634 -2.223 0 0 -3.634 -2.223 -2.900 -0.751 2011 1 -7.201 -2.462 0 0 -7.201 -2.462 -6.883 -1.406 2011 2 -5.093 -0.528 0 0 -5.093 -0.528 -5.178 0.126 2011 3 -1.806 -1.485 0 0 -1.806 -1.485 -1.762 -0.702 2011 4 5.198 -0.684 0 0 5.198 -0.684 5.287 0.143 2011 5 12.412 1.107 0 0 12.412 1.107 10.617 0.050 2011 6 18.617 1.993 0 0 18.617 1.993 15.959 0.074 2011 7 24.152 4.350 0 0 24.152 4.350 21.610 2.546 2011 8 22.129 2.458 0 0 22.129 2.458 20.139 1.207 2011 9 16.902 0.776 0 0 16.902 0.776 16.170 0.783 2011 10 11.577 0.840 0 0 11.577 0.840 11.375 1.377 2011 11 6.250 1.336 0 0 6.250 1.336 7.376 3.201 2011 12 0.464 1.875 0 0 0.464 1.875 0.909 3.058 2012 1 -2.197 2.541 0 0 -2.197 2.541 -1.983 3.494 2012 2 -0.847 3.719 0 0 -0.847 3.719 -1.151 4.153 2012 3 6.272 6.594 0 0 6.272 6.594 6.599 7.659 2012 4 7.424 1.542 0 0 7.424 1.542 6.146 1.002 2012 5 15.536 4.230 0 0 15.536 4.230 13.110 2.543 2012 6 20.409 3.786 0 0 20.409 3.786 17.838 1.953 2012 7 24.289 4.486 0 0 24.289 4.486 21.710 2.647 2012 8 21.477 1.806 0 0 21.477 1.806 19.935 1.002 2012 9 16.991 0.865 0 0 16.991 0.865 15.682 0.295 2012 10 10.339 -0.398 0 0 10.339 -0.398 10.645 0.646 2012 11 3.500 -1.414 0 0 3.500 -1.414 4.677 0.502 2012 12 0.952 2.363 0 0 0.952 2.363 1.272 3.421 2013 1 -3.179 1.559 0 0 -3.179 1.559 -3.074 2.403 2013 2 -4.649 -0.083 0 0 -4.649 -0.083 -4.686 0.618 2013 3 -1.174 -0.852 0 0 -1.174 -0.852 -0.831 0.229 2013 4 4.865 -1.018 0 0 4.865 -1.018 4.582 -0.562 2013 5 13.914 2.608 0 0 13.914 2.608 11.729 1.162 2013 6 18.539 1.915 0 0 18.539 1.915 15.953 0.068 2013 7 22.950 3.148 1 0 NaN NaN 19.785 0.722 2013 8 23.574 3.902 1 0 NaN NaN 19.035 0.103 2013 9 17.269 1.143 1 0 NaN NaN 15.687 0.300 2013 10 11.492 0.755 0 0 11.492 0.755 11.355 1.357 2013 11 7.707 2.793 1 0 NaN NaN NaN NaN
