% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 173885 % Primary Name: MARY ISLAND % Record Type: TAVG % Country: United States % State: AK % Latitude: 55.09900 +/- 0.00050 % Longitude: -131.18200 +/- 0.00050 % Elevation (m): 4.00 +/- 0.05 % # of Months: 13 % % IDs: gsod - 997179-99999 % icao - MRYA2 % ncdc - 20021786 % usaf - 997179 % % Sources: Global Summary of the Day % Multi-network Metadata System % % Site Hash: a932dfe2197edea1cbef6e23a8d08d29 % Raw Data Hash: 1dffe5487e5e82037e1e6d283d92fd16 % Adj Data Hash: 5934a39ff00226c354b1029bf083bcc1 % % 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 11 NaN NaN NaN NaN NaN NaN -1.567 -0.879 2011 12 NaN NaN NaN NaN NaN NaN -1.608 2.249 2012 1 NaN NaN NaN NaN NaN NaN -5.419 0.449 2012 2 NaN NaN NaN NaN NaN NaN 0.067 2.734 2012 3 NaN NaN NaN NaN NaN NaN -0.591 0.186 2012 4 NaN NaN NaN NaN NaN NaN 3.520 0.774 2012 5 NaN NaN NaN NaN NaN NaN 6.187 -0.874 2012 6 NaN NaN NaN NaN NaN NaN 9.646 -0.841 2012 7 NaN NaN NaN NaN NaN NaN 12.581 -0.007 2012 8 NaN NaN NaN NaN NaN NaN 12.798 0.543 2012 9 NaN NaN NaN NaN NaN NaN 9.589 0.554 2012 10 NaN NaN NaN NaN NaN NaN 2.984 -1.184 2012 11 4.118 -0.001 1 0 NaN NaN -0.212 0.476 2012 12 3.480 2.530 0 0 3.480 2.530 -3.880 -0.023 2013 1 4.816 5.878 1 0 NaN NaN -2.426 3.443 2013 2 6.285 4.145 1 0 NaN NaN 1.061 3.727 2013 3 5.137 1.107 0 0 5.137 1.107 -0.387 0.390 2013 4 7.565 0.012 0 0 7.565 0.012 2.782 0.037 2013 5 12.176 0.307 1 0 NaN NaN 8.594 1.532 2013 6 15.652 0.358 0 0 15.652 0.358 12.320 1.833 2013 7 17.289 -0.106 0 0 17.289 -0.106 13.728 1.140 2013 8 17.303 0.241 0 0 17.303 0.241 13.748 1.493 2013 9 16.249 2.407 1 0 NaN NaN 10.635 1.600 2013 10 11.185 2.210 0 0 11.185 2.210 5.650 1.482 2013 11 7.596 3.477 1 0 NaN NaN NaN NaN
