% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 43051 % Primary Name: KETCHIKAN % Record Type: TAVG % Country: United States % State: AK % Latitude: 55.33300 +/- 0.00050 % Longitude: -131.62500 +/- 0.00050 % Elevation (m): 3.00 +/- 0.05 % # of Months: 55 % % IDs: gsod - 998258-99999 % icao - KECA2 % usaf - 998258 % % Sources: Global Summary of the Day % % Site Hash: a42b5bdeade8080b5f6ade1f8b7f9cb3 % Raw Data Hash: 0da015e96b30c6db0d80f6d8d69f3bd9 % Adj Data Hash: 3f27a49194ee1b1f81452fe0c99738ed % % 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 5 NaN NaN NaN NaN NaN NaN 7.882 0.821 2008 6 NaN NaN NaN NaN NaN NaN 9.545 -0.942 2008 7 NaN NaN NaN NaN NaN NaN 11.642 -0.946 2008 8 NaN NaN NaN NaN NaN NaN 12.529 0.274 2008 9 NaN NaN NaN NaN NaN NaN 9.862 0.827 2008 10 NaN NaN NaN NaN NaN NaN 4.187 0.019 2008 11 NaN NaN NaN NaN NaN NaN 1.154 1.842 2008 12 NaN NaN NaN NaN NaN NaN -6.322 -2.465 2009 1 NaN NaN NaN NaN NaN NaN -4.903 0.965 2009 2 NaN NaN NaN NaN NaN NaN -2.906 -0.239 2009 3 NaN NaN NaN NaN NaN NaN -2.214 -1.438 2009 4 NaN NaN NaN NaN NaN NaN 2.741 -0.005 2009 5 9.036 -1.127 1 0 NaN NaN 7.421 0.360 2009 6 12.943 -0.645 0 0 12.943 -0.645 11.955 1.469 2009 7 15.290 -0.398 0 0 15.290 -0.398 14.884 2.296 2009 8 15.032 -0.324 0 0 15.032 -0.324 13.561 1.306 2009 9 12.117 -0.019 0 0 12.117 -0.019 9.940 0.906 2009 10 8.530 1.261 0 0 8.530 1.261 4.658 0.490 2009 11 5.074 2.661 0 0 5.074 2.661 0.096 0.784 2009 12 1.294 2.050 0 0 1.294 2.050 -5.746 -1.889 2010 1 5.434 8.201 0 0 5.434 8.201 -1.863 4.005 2010 2 5.083 4.649 0 0 5.083 4.649 1.927 4.594 2010 3 4.410 2.086 0 0 4.410 2.086 1.553 2.330 2010 4 6.174 0.327 0 0 6.174 0.327 3.986 1.240 2010 5 9.638 -0.525 0 0 9.638 -0.525 8.739 1.677 2010 6 11.575 -2.013 0 0 11.575 -2.013 10.726 0.239 2010 7 14.237 -1.452 0 0 14.237 -1.452 13.168 0.580 2010 8 15.048 -0.307 0 0 15.048 -0.307 13.507 1.252 2010 9 12.241 0.106 0 0 12.241 0.106 9.911 0.876 2010 10 9.025 1.756 0 0 9.025 1.756 5.389 1.221 2010 11 4.657 2.245 0 0 4.657 2.245 -0.750 -0.062 2010 12 3.195 3.952 0 0 3.195 3.952 -3.049 0.809 2011 1 2.495 5.262 0 0 2.495 5.262 -4.168 1.700 2011 2 1.220 0.786 0 0 1.220 0.786 -3.433 -0.766 2011 3 3.611 1.287 0 0 3.611 1.287 -0.502 0.275 2011 4 4.920 -0.926 0 0 4.920 -0.926 2.381 -0.365 2011 5 8.409 -1.753 1 0 NaN NaN 7.627 0.565 2011 6 12.342 -1.245 1 0 NaN NaN 10.980 0.493 2011 7 12.900 -2.789 0 0 12.900 -2.789 11.871 -0.717 2011 8 13.332 -2.024 0 0 13.332 -2.024 11.663 -0.592 2011 9 12.146 0.011 0 0 12.146 0.011 9.668 0.633 2011 10 8.303 1.034 0 0 8.303 1.034 4.654 0.485 2011 11 3.259 0.847 0 0 3.259 0.847 -1.567 -0.879 2011 12 3.346 4.102 0 0 3.346 4.102 -1.608 2.249 2012 1 1.066 3.834 0 0 1.066 3.834 -5.419 0.449 2012 2 3.490 3.056 0 0 3.490 3.056 0.067 2.734 2012 3 2.677 0.353 0 0 2.677 0.353 -0.591 0.186 2012 4 6.228 0.381 0 0 6.228 0.381 3.520 0.774 2012 5 7.701 -2.462 0 0 7.701 -2.462 6.187 -0.874 2012 6 10.988 -2.599 0 0 10.988 -2.599 9.646 -0.841 2012 7 13.407 -2.282 0 0 13.407 -2.282 12.581 -0.007 2012 8 13.694 -1.662 0 0 13.694 -1.662 12.798 0.543 2012 9 11.637 -0.499 0 0 11.637 -0.499 9.589 0.554 2012 10 6.740 -0.529 0 0 6.740 -0.529 2.984 -1.184 2012 11 5.009 2.597 0 0 5.009 2.597 -0.212 0.476 2012 12 2.170 2.927 0 0 2.170 2.927 -3.880 -0.023 2013 1 3.928 6.696 0 0 3.928 6.696 -2.426 3.443 2013 2 4.282 3.848 0 0 4.282 3.848 1.061 3.727 2013 3 3.013 0.688 0 0 3.013 0.688 -0.387 0.390 2013 4 5.563 -0.284 0 0 5.563 -0.284 2.782 0.037 2013 5 9.613 -0.550 0 0 9.613 -0.550 8.594 1.532 2013 6 13.180 -0.408 0 0 13.180 -0.408 12.320 1.833 2013 7 14.756 -0.932 0 0 14.756 -0.932 13.728 1.140 2013 8 14.912 -0.444 0 0 14.912 -0.444 13.748 1.493 2013 9 12.863 0.727 0 0 12.863 0.727 10.635 1.600 2013 10 9.219 1.950 0 0 9.219 1.950 5.650 1.482 2013 11 5.869 3.456 1 0 NaN NaN NaN NaN
