% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 43426 % Primary Name: CHEVAK AIRPORT % Record Type: TAVG % Country: United States % State: AK % Latitude: 61.53300 +/- 0.00050 % Longitude: -165.58300 +/- 0.00050 % Elevation (m): 23.00 +/- 0.05 % # of Months: 57 % % IDs: gsod - 701338-99999 % icao - PAVA % usaf - 701338 % % Sources: Global Summary of the Day % % Site Hash: d7de48556b15d298703eb4df31db8b69 % Raw Data Hash: 80b2a6e2afee156a72eaf41c1d45b3e8 % Adj Data Hash: 62ef78f6d871bbe3ef4799a091a927cd % % 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 2 NaN NaN NaN NaN NaN NaN -17.598 -3.607 2008 3 NaN NaN NaN NaN NaN NaN -11.564 -0.368 2008 4 NaN NaN NaN NaN NaN NaN -5.697 -0.574 2008 5 NaN NaN NaN NaN NaN NaN 5.223 0.898 2008 6 NaN NaN NaN NaN NaN NaN 10.355 0.078 2008 7 NaN NaN NaN NaN NaN NaN 12.015 -0.934 2008 8 NaN NaN NaN NaN NaN NaN 11.732 0.073 2008 9 NaN NaN NaN NaN NaN NaN 8.710 1.679 2008 10 NaN NaN NaN NaN NaN NaN -5.079 -3.503 2008 11 NaN NaN NaN NaN NaN NaN -10.831 -2.529 2008 12 NaN NaN NaN NaN NaN NaN -11.757 3.489 2009 1 NaN NaN NaN NaN NaN NaN -16.257 -2.038 2009 2 -9.459 5.286 1 0 NaN NaN -13.309 0.683 2009 3 -12.321 -0.372 0 0 -12.321 -0.372 -12.506 -1.310 2009 4 -9.649 -3.773 1 0 NaN NaN -5.591 -0.467 2009 5 NaN NaN NaN NaN NaN NaN 4.618 0.293 2009 6 5.500 -4.024 1 0 NaN NaN 10.864 0.587 2009 7 11.978 -0.219 1 0 NaN NaN 14.330 1.381 2009 8 11.769 0.864 1 0 NaN NaN 11.851 0.193 2009 9 6.996 0.718 0 0 6.996 0.718 7.806 0.775 2009 10 1.491 3.819 0 0 1.491 3.819 0.558 2.133 2009 11 -12.267 -3.212 1 0 NaN NaN -10.644 -2.342 2009 12 -3.421 12.577 1 0 NaN NaN -10.046 5.200 2010 1 -15.355 -0.383 0 0 -15.355 -0.383 -15.374 -1.155 2010 2 -11.816 2.929 1 0 NaN NaN -11.628 2.363 2010 3 -17.315 -5.366 0 0 -17.315 -5.366 -15.943 -4.748 2010 4 -6.648 -0.772 0 0 -6.648 -0.772 -5.303 -0.180 2010 5 3.470 -0.103 0 0 3.470 -0.103 6.294 1.969 2010 6 6.954 -2.570 0 0 6.954 -2.570 9.795 -0.481 2010 7 10.729 -1.467 0 0 10.729 -1.467 13.093 0.144 2010 8 10.756 -0.149 0 0 10.756 -0.149 12.521 0.863 2010 9 8.500 2.221 0 0 8.500 2.221 9.362 2.331 2010 10 0.667 2.995 0 0 0.667 2.995 -0.426 1.149 2010 11 -4.400 4.655 0 0 -4.400 4.655 -4.886 3.416 2010 12 -13.102 2.896 1 0 NaN NaN -15.601 -0.356 2011 1 -10.946 4.025 0 0 -10.946 4.025 -10.070 4.149 2011 2 -11.300 3.445 0 0 -11.300 3.445 -11.421 2.571 2011 3 -10.213 1.736 0 0 -10.213 1.736 -8.758 2.438 2011 4 -7.087 -1.211 0 0 -7.087 -1.211 -5.616 -0.493 2011 5 3.266 -0.307 1 0 NaN NaN 6.871 2.546 2011 6 8.844 -0.680 0 0 8.844 -0.680 11.408 1.131 2011 7 8.652 -3.544 0 0 8.652 -3.544 11.323 -1.626 2011 8 9.122 -1.784 0 0 9.122 -1.784 10.859 -0.800 2011 9 7.450 1.171 0 0 7.450 1.171 8.292 1.261 2011 10 0.310 2.638 0 0 0.310 2.638 -0.788 0.788 2011 11 -9.558 -0.503 0 0 -9.558 -0.503 -11.295 -2.993 2011 12 -8.182 7.817 0 0 -8.182 7.817 -13.119 2.126 2012 1 -24.161 -9.189 0 0 -24.161 -9.189 -24.796 -10.577 2012 2 -10.952 3.792 0 0 -10.952 3.792 -10.990 3.002 2012 3 -15.711 -3.762 0 0 -15.711 -3.762 -15.842 -4.646 2012 4 -5.496 0.380 1 0 NaN NaN -3.850 1.274 2012 5 -0.510 -4.082 0 0 -0.510 -4.082 2.937 -1.388 2012 6 7.329 -2.195 0 0 7.329 -2.195 10.002 -0.274 2012 7 9.514 -2.682 0 0 9.514 -2.682 12.152 -0.797 2012 8 10.436 -0.469 0 0 10.436 -0.469 12.129 0.471 2012 9 5.069 -1.210 0 0 5.069 -1.210 5.966 -1.065 2012 10 0.670 2.998 0 0 0.670 2.998 -0.618 0.957 2012 11 -8.676 0.378 0 0 -8.676 0.378 -9.580 -1.278 2012 12 -15.099 0.900 0 0 -15.099 0.900 -16.945 -1.699 2013 1 -13.185 1.787 1 0 NaN NaN -9.300 4.919 2013 2 -16.774 -2.029 0 0 -16.774 -2.029 -16.561 -2.569 2013 3 -11.805 0.144 0 0 -11.805 0.144 -11.341 -0.145 2013 4 -7.850 -1.974 0 0 -7.850 -1.974 -6.819 -1.696 2013 5 -0.208 -3.780 0 0 -0.208 -3.780 2.575 -1.750 2013 6 8.756 -0.768 0 0 8.756 -0.768 12.062 1.785 2013 7 11.159 -1.037 0 0 11.159 -1.037 13.896 0.947 2013 8 11.473 0.568 0 0 11.473 0.568 13.213 1.554 2013 9 6.917 0.638 0 0 6.917 0.638 7.119 0.088 2013 10 3.402 5.730 0 0 3.402 5.730 2.349 3.924 2013 11 -1.293 7.761 1 0 NaN NaN NaN NaN
