% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 32270 % Primary Name: HALF MOON BAY AIRPOR % Record Type: TAVG % Country: United States % State: CA % Latitude: 37.51300 +/- 0.00050 % Longitude: -122.50100 +/- 0.00050 % Elevation (m): 20.00 +/- 0.05 % # of Months: 53 % % IDs: gsod - 720646-99999 % icao - KHAF % usaf - 720646 % % Sources: Global Summary of the Day % % Site Hash: f63160c8351a972fc9061c776d4b3c6a % Raw Data Hash: 26999d9f07d184d9eb369ae8d4542a1f % Adj Data Hash: c2145e9fa09ebc8fa38de4ae9ca74223 % % 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 7 NaN NaN NaN NaN NaN NaN 20.298 0.709 2008 8 NaN NaN NaN NaN NaN NaN 20.708 1.184 2008 9 NaN NaN NaN NaN NaN NaN 20.442 1.305 2008 10 NaN NaN NaN NaN NaN NaN 17.566 1.310 2008 11 NaN NaN NaN NaN NaN NaN 13.765 1.732 2008 12 NaN NaN NaN NaN NaN NaN 7.974 -0.625 2009 1 NaN NaN NaN NaN NaN NaN 10.067 1.767 2009 2 NaN NaN NaN NaN NaN NaN 10.610 0.128 2009 3 NaN NaN NaN NaN NaN NaN 11.583 -0.058 2009 4 NaN NaN NaN NaN NaN NaN 13.402 0.191 2009 5 NaN NaN NaN NaN NaN NaN 16.954 1.167 2009 6 NaN NaN NaN NaN NaN NaN 18.241 0.048 2009 7 13.340 -3.182 1 0 NaN NaN 19.867 0.278 2009 8 14.826 -1.631 0 0 14.826 -1.631 20.476 0.952 2009 9 14.320 -1.749 0 0 14.320 -1.749 21.353 2.216 2009 10 13.238 0.049 0 0 13.238 0.049 16.176 -0.080 2009 11 11.780 2.813 0 0 11.780 2.813 12.389 0.356 2009 12 9.590 4.058 0 0 9.590 4.058 8.333 -0.265 2010 1 11.032 5.799 0 0 11.032 5.799 9.542 1.241 2010 2 11.373 3.958 0 0 11.373 3.958 11.681 1.199 2010 3 10.767 2.194 0 0 10.767 2.194 11.832 0.191 2010 4 10.643 0.499 0 0 10.643 0.499 12.058 -1.153 2010 5 11.263 -1.457 0 0 11.263 -1.457 14.372 -1.415 2010 6 12.669 -2.459 0 0 12.669 -2.459 18.457 0.263 2010 7 13.165 -3.358 0 0 13.165 -3.358 19.144 -0.445 2010 8 13.314 -3.143 0 0 13.314 -3.143 18.699 -0.824 2010 9 13.750 -2.320 0 0 13.750 -2.320 20.431 1.294 2010 10 13.208 0.019 0 0 13.208 0.019 16.889 0.633 2010 11 11.109 2.143 0 0 11.109 2.143 12.084 0.051 2010 12 10.839 5.307 0 0 10.839 5.307 10.200 1.602 2011 1 10.797 5.564 0 0 10.797 5.564 9.262 0.962 2011 2 9.308 1.892 0 0 9.308 1.892 10.044 -0.438 2011 3 10.860 2.287 0 0 10.860 2.287 11.408 -0.233 2011 4 11.130 0.986 0 0 11.130 0.986 12.998 -0.213 2011 5 11.961 -0.759 0 0 11.961 -0.759 14.373 -1.414 2011 6 13.439 -1.688 0 0 13.439 -1.688 17.338 -0.856 2011 7 14.133 -2.390 0 0 14.133 -2.390 19.648 0.058 2011 8 13.885 -2.572 0 0 13.885 -2.572 19.318 -0.205 2011 9 13.709 -2.361 0 0 13.709 -2.361 20.917 1.780 2011 10 13.994 0.805 0 0 13.994 0.805 17.564 1.308 2011 11 10.909 1.943 0 0 10.909 1.943 11.480 -0.553 2011 12 8.934 3.402 0 0 8.934 3.402 9.095 0.497 2012 1 9.989 4.756 0 0 9.989 4.756 9.985 1.685 2012 2 9.973 2.558 0 0 9.973 2.558 11.350 0.868 2012 3 9.686 1.113 1 0 NaN NaN 11.064 -0.576 2012 4 11.144 1.001 0 0 11.144 1.001 13.855 0.645 2012 5 10.925 -1.795 0 0 10.925 -1.795 16.358 0.571 2012 6 12.487 -2.640 0 0 12.487 -2.640 18.222 0.028 2012 7 13.179 -3.343 0 0 13.179 -3.343 19.305 -0.285 2012 8 13.118 -3.339 0 0 13.118 -3.339 20.038 0.514 2012 9 12.320 -3.749 0 0 12.320 -3.749 19.086 -0.050 2012 10 14.080 0.890 0 0 14.080 0.890 17.519 1.263 2012 11 13.230 4.263 0 0 13.230 4.263 13.490 1.457 2012 12 10.326 4.795 0 0 10.326 4.795 9.233 0.635 2013 1 9.513 4.279 0 0 9.513 4.279 8.349 0.049 2013 2 8.835 1.420 0 0 8.835 1.420 10.474 -0.008 2013 3 9.763 1.190 1 0 NaN NaN 12.973 1.333 2013 4 10.850 0.706 0 0 10.850 0.706 15.518 2.307 2013 5 12.195 -0.525 1 0 NaN NaN 17.191 1.404 2013 6 13.037 -2.090 0 0 13.037 -2.090 19.365 1.171 2013 7 13.421 -3.101 0 0 13.421 -3.101 20.141 0.552 2013 8 14.928 -1.529 0 0 14.928 -1.529 19.751 0.227 2013 9 15.150 -0.920 0 0 15.150 -0.920 19.971 0.835 2013 10 12.373 -0.816 0 0 12.373 -0.816 16.460 0.204 2013 11 10.910 1.944 1 0 NaN NaN NaN NaN
