% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 172495 % Primary Name: CHATHAM IS AERO AWS % Record Type: TAVG % Country: New Zealand % Latitude: -43.81700 +/- 0.00050 % Longitude: -176.47500 +/- 0.00050 % Elevation (m): 12.00 +/- 0.05 % # of Months: 14 % % IDs: gsod - 939850-99999 % usaf - 939850 % % Sources: Global Summary of the Day % % Site Hash: 1ad927bdcb15fc8a8fc606bb6ae5d2f9 % Raw Data Hash: cbb8083909f1f735c116f0f62c82c00d % Adj Data Hash: 9a1409e489ea38ae368c6c151ea5a5bf % % 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 10 NaN NaN NaN NaN NaN NaN 10.441 0.176 2011 11 NaN NaN NaN NaN NaN NaN 11.530 -0.170 2011 12 NaN NaN NaN NaN NaN NaN 13.335 -0.061 2012 1 NaN NaN NaN NaN NaN NaN 14.921 0.459 2012 2 NaN NaN NaN NaN NaN NaN 14.240 -0.656 2012 3 NaN NaN NaN NaN NaN NaN 14.027 -0.107 2012 4 NaN NaN NaN NaN NaN NaN 13.076 0.696 2012 5 NaN NaN NaN NaN NaN NaN 10.453 0.047 2012 6 NaN NaN NaN NaN NaN NaN 8.392 -0.123 2012 7 NaN NaN NaN NaN NaN NaN 8.288 0.539 2012 8 NaN NaN NaN NaN NaN NaN 8.914 0.559 2012 9 NaN NaN NaN NaN NaN NaN 10.014 0.652 2012 10 11.075 0.545 0 0 11.075 0.545 10.650 0.384 2012 11 11.269 -0.697 0 0 11.269 -0.697 10.973 -0.727 2012 12 14.572 0.910 0 0 14.572 0.910 14.533 1.136 2013 1 16.185 1.457 0 0 16.185 1.457 15.619 1.157 2013 2 15.896 0.735 1 0 NaN NaN 15.256 0.360 2013 3 14.704 0.306 0 0 14.704 0.306 14.740 0.607 2013 4 14.019 1.373 0 0 14.019 1.373 13.628 1.247 2013 5 11.097 0.426 0 0 11.097 0.426 10.956 0.550 2013 6 9.841 1.061 0 0 9.841 1.061 9.375 0.860 2013 7 8.918 0.903 0 0 8.918 0.903 8.724 0.975 2013 8 9.878 1.258 0 0 9.878 1.258 9.738 1.383 2013 9 10.191 0.563 0 0 10.191 0.563 10.035 0.673 2013 10 11.998 1.468 0 0 11.998 1.468 11.595 1.329 2013 11 11.678 -0.288 1 0 NaN NaN NaN NaN
