% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 157704 % Primary Name: ALKHOR AIRPORT % Record Type: TAVG % Country: Qatar % Latitude: 25.61700 +/- 0.00050 % Longitude: 51.51700 +/- 0.00050 % Elevation (m): 11.00 +/- 0.05 % # of Months: 22 % % IDs: gsod - 411610-99999 % usaf - 411610 % wmo - 41161 % % Sources: Global Summary of the Day % World Meteorological Organization Metadata % % Site Hash: 81337c19601d32ec44eda3faea804d1b % Raw Data Hash: 61fe05d10046d738a8a56ee6472351d2 % Adj Data Hash: ed10315d10d3214d0eeed4357d5f0a24 % % 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 2011 1 NaN NaN NaN NaN NaN NaN 18.496 1.796 2011 2 NaN NaN NaN NaN NaN NaN 19.374 1.345 2011 3 NaN NaN NaN NaN NaN NaN 22.344 0.739 2011 4 NaN NaN NaN NaN NaN NaN 27.220 1.553 2011 5 NaN NaN NaN NaN NaN NaN 33.558 2.898 2011 6 NaN NaN NaN NaN NaN NaN 35.592 2.067 2011 7 NaN NaN NaN NaN NaN NaN 36.092 1.573 2011 8 NaN NaN NaN NaN NaN NaN 36.066 1.833 2011 9 NaN NaN NaN NaN NaN NaN 33.712 1.650 2011 10 NaN NaN NaN NaN NaN NaN 29.270 0.956 2011 11 NaN NaN NaN NaN NaN NaN 23.057 -0.456 2011 12 NaN NaN NaN NaN NaN NaN 17.100 -1.464 2012 1 15.730 1.128 1 0 NaN NaN 16.983 0.282 2012 2 16.327 0.397 0 0 16.327 0.397 18.397 0.368 2012 3 19.124 -0.382 1 0 NaN NaN 21.365 -0.240 2012 4 25.545 1.977 1 0 NaN NaN 26.640 0.973 2012 5 32.064 3.503 0 0 32.064 3.503 34.046 3.387 2012 6 33.289 1.864 0 0 33.289 1.864 35.124 1.599 2012 7 34.482 2.062 1 0 NaN NaN 36.692 2.173 2012 8 33.914 1.779 0 0 33.914 1.779 36.423 2.190 2012 9 31.559 1.595 1 0 NaN NaN 33.569 1.506 2012 10 28.189 1.973 1 0 NaN NaN 30.061 1.747 2012 11 24.772 3.358 1 0 NaN NaN 25.254 1.742 2012 12 19.410 2.945 1 0 NaN NaN 20.098 1.534 2013 1 17.174 2.572 1 0 NaN NaN 18.700 2.000 2013 2 18.079 2.149 1 0 NaN NaN 19.879 1.850 2013 3 20.608 1.101 1 0 NaN NaN 23.299 1.694 2013 4 25.992 2.424 1 0 NaN NaN 27.348 1.681 2013 5 30.548 1.987 1 0 NaN NaN 31.337 0.678 2013 6 33.201 1.776 1 0 NaN NaN 33.883 0.359 2013 7 34.571 2.151 1 0 NaN NaN 35.781 1.262 2013 8 32.386 0.251 1 0 NaN NaN 35.287 1.053 2013 9 30.610 0.646 1 0 NaN NaN 33.306 1.244 2013 10 26.403 0.188 1 0 NaN NaN 28.121 -0.193
