% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 43015 % Primary Name: CHUGINADAK ISLAND ALASKA % Record Type: TAVG % Country: United States % State: AK % Latitude: 52.83300 +/- 0.00050 % Longitude: -169.83300 +/- 0.00050 % Elevation (m): 24.00 +/- 0.05 % # of Months: 12 % % IDs: gsod - 749200-99999 % usaf - 749200 % % Sources: Global Summary of the Day % % Site Hash: 27d5124272f2035473c9c1caec6fc3bb % Raw Data Hash: 83fb74a767417ec96e80e36e5d636984 % Adj Data Hash: cf21e6107942106516d1adc923e70394 % % 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 1942 7 NaN NaN NaN NaN NaN NaN 9.620 0.329 1942 8 NaN NaN NaN NaN NaN NaN 11.099 0.579 1942 9 NaN NaN NaN NaN NaN NaN 10.281 1.235 1942 10 NaN NaN NaN NaN NaN NaN 5.910 0.281 1942 11 NaN NaN NaN NaN NaN NaN 4.182 0.462 1942 12 NaN NaN NaN NaN NaN NaN 0.393 -1.730 1943 1 NaN NaN NaN NaN NaN NaN 1.249 -0.429 1943 2 NaN NaN NaN NaN NaN NaN 0.504 -0.300 1943 3 NaN NaN NaN NaN NaN NaN 1.906 0.417 1943 4 NaN NaN NaN NaN NaN NaN 1.358 -1.036 1943 5 NaN NaN NaN NaN NaN NaN 4.584 0.310 1943 6 NaN NaN NaN NaN NaN NaN 7.230 0.588 1943 7 9.109 -0.181 0 0 9.109 -0.181 9.147 -0.145 1943 8 11.618 1.100 0 0 11.618 1.100 12.058 1.538 1943 9 8.452 -0.594 0 0 8.452 -0.594 8.593 -0.453 1943 10 6.391 0.762 0 0 6.391 0.762 6.042 0.412 1943 11 3.276 -0.443 0 0 3.276 -0.443 3.301 -0.419 1943 12 0.088 -2.034 0 0 0.088 -2.034 0.184 -1.938 1944 1 -0.332 -2.009 0 0 -0.332 -2.009 0.068 -1.610 1944 2 1.466 0.663 1 0 NaN NaN 1.743 0.939 1944 3 1.308 -0.180 0 0 1.308 -0.180 1.068 -0.421 1944 4 2.880 0.487 0 0 2.880 0.487 2.523 0.129 1944 5 4.419 0.146 0 0 4.419 0.146 4.235 -0.040 1944 6 6.279 -0.362 1 0 NaN NaN 6.507 -0.135 1944 7 NaN NaN NaN NaN NaN NaN 8.648 -0.644 1944 8 NaN NaN NaN NaN NaN NaN 10.983 0.464 1944 9 NaN NaN NaN NaN NaN NaN 8.860 -0.187 1944 10 NaN NaN NaN NaN NaN NaN 5.741 0.111 1944 11 NaN NaN NaN NaN NaN NaN 4.731 1.011 1944 12 NaN NaN NaN NaN NaN NaN 2.690 0.567 1945 1 NaN NaN NaN NaN NaN NaN 2.397 0.719 1945 2 NaN NaN NaN NaN NaN NaN 1.482 0.678 1945 3 NaN NaN NaN NaN NaN NaN 0.610 -0.879 1945 4 NaN NaN NaN NaN NaN NaN 3.507 1.113 1945 5 NaN NaN NaN NaN NaN NaN 4.872 0.597 1945 6 NaN NaN NaN NaN NaN NaN 6.545 -0.097
