% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 11177 % Primary Name: ALERT (READAC) % Record Type: TAVG % Country: Canada % Latitude: 82.50000 +/- 0.00050 % Longitude: -62.36700 +/- 0.00050 % Elevation (m): 92.00 +/- 0.05 % # of Months: 14 % % IDs: gsod - 710824-99999 % icao - ZLR % usaf - 710824 % % Sources: Global Summary of the Day % % Site Hash: 75c6d5a5edd8d2c07ee73c89fd347591 % Raw Data Hash: becac9e949e049e845c47c011fba1ecb % Adj Data Hash: 317b692e8fd5c245900e3dc7c9984f04 % % 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 1990 11 NaN NaN NaN NaN NaN NaN -27.794 -4.344 1990 12 NaN NaN NaN NaN NaN NaN -28.968 -1.494 1991 1 NaN NaN NaN NaN NaN NaN -31.899 -2.093 1991 2 NaN NaN NaN NaN NaN NaN -31.096 0.387 1991 3 NaN NaN NaN NaN NaN NaN -28.987 2.573 1991 4 NaN NaN NaN NaN NaN NaN -23.348 1.135 1991 5 NaN NaN NaN NaN NaN NaN -10.877 1.429 1991 6 NaN NaN NaN NaN NaN NaN -1.852 1.573 1991 7 NaN NaN NaN NaN NaN NaN 0.170 0.100 1991 8 NaN NaN NaN NaN NaN NaN 0.834 1.986 1991 9 NaN NaN NaN NaN NaN NaN -6.524 2.506 1991 10 NaN NaN NaN NaN NaN NaN -16.009 1.243 1991 11 -23.885 0.298 0 0 -23.885 0.298 -20.389 3.060 1991 12 -31.224 -3.016 0 0 -31.224 -3.016 -28.348 -0.873 1992 1 -34.460 -3.921 0 0 -34.460 -3.921 -31.988 -2.182 1992 2 -34.542 -2.326 0 0 -34.542 -2.326 -31.538 -0.055 1992 3 -29.493 2.801 0 0 -29.493 2.801 -28.948 2.612 1992 4 -27.296 -2.080 0 0 -27.296 -2.080 -26.442 -1.959 1992 5 -14.070 -1.031 0 0 -14.070 -1.031 -13.733 -1.428 1992 6 -2.556 1.604 0 0 -2.556 1.604 -4.696 -1.270 1992 7 2.496 3.160 0 0 2.496 3.160 -1.047 -1.117 1992 8 -0.471 1.414 0 0 -0.471 1.414 -1.730 -0.578 1992 9 -8.696 1.067 0 0 -8.696 1.067 -8.786 0.243 1992 10 -19.672 -1.686 0 0 -19.672 -1.686 -17.421 -0.169 1992 11 -28.475 -4.292 1 0 NaN NaN -24.738 -1.288 1992 12 -28.838 -0.629 1 0 NaN NaN -27.466 0.008 1993 1 NaN NaN NaN NaN NaN NaN -31.482 -1.677 1993 2 NaN NaN NaN NaN NaN NaN -27.927 3.555 1993 3 NaN NaN NaN NaN NaN NaN -32.836 -1.276 1993 4 NaN NaN NaN NaN NaN NaN -23.631 0.851 1993 5 NaN NaN NaN NaN NaN NaN -10.973 1.332 1993 6 NaN NaN NaN NaN NaN NaN -3.863 -0.438 1993 7 NaN NaN NaN NaN NaN NaN 1.441 1.370 1993 8 NaN NaN NaN NaN NaN NaN -0.578 0.574 1993 9 NaN NaN NaN NaN NaN NaN -10.043 -1.014 1993 10 NaN NaN NaN NaN NaN NaN -15.371 1.882 1993 11 NaN NaN NaN NaN NaN NaN -23.839 -0.390 1993 12 NaN NaN NaN NaN NaN NaN -29.107 -1.632
