% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 43670 % Primary Name: PEARL CREEK % Record Type: TAVG % Country: United States % State: AK % Latitude: 64.89220 +/- 0.00005 % Longitude: -147.79610 +/- 0.00005 % Elevation (m): 229.80 +/- 0.05 % # of Months: 17 % % IDs: coop - 507108 % ghcnd - USC00507108 % ncdc - 30000192 % % Sources: US Cooperative Summary of the Day % Global Historical Climatology Network - Daily % US Cooperative Summary of the Month % Multi-network Metadata System % % Site Hash: 93f0e4cfca58c22c79583567c1c2ba5d % Raw Data Hash: 7ffc14e2edee2b513b13fffac3be35ea % Adj Data Hash: 21f358d6b43a5644f76bc632b7fe1876 % % 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 1996 2 NaN NaN NaN NaN NaN NaN -20.867 0.625 1996 3 NaN NaN NaN NaN NaN NaN -11.096 3.567 1996 4 NaN NaN NaN NaN NaN NaN -2.596 0.936 1996 5 NaN NaN NaN NaN NaN NaN 7.119 0.473 1996 6 NaN NaN NaN NaN NaN NaN 13.004 0.080 1996 7 NaN NaN NaN NaN NaN NaN 15.217 0.933 1996 8 NaN NaN NaN NaN NaN NaN 9.665 -1.937 1996 9 NaN NaN NaN NaN NaN NaN 3.727 -1.133 1996 10 NaN NaN NaN NaN NaN NaN -12.629 -6.226 1996 11 NaN NaN NaN NaN NaN NaN -19.309 -1.886 1996 12 NaN NaN NaN NaN NaN NaN -25.839 -1.059 1997 1 NaN NaN NaN NaN NaN NaN -28.013 -2.003 1997 2 -5.778 11.855 0 0 -5.778 11.855 -12.153 9.339 1997 3 -11.979 -1.175 1 0 NaN NaN -17.570 -2.908 1997 4 2.889 2.562 0 0 2.889 2.562 -0.898 2.634 1997 5 9.931 -0.573 1 0 NaN NaN 7.198 0.553 1997 6 16.321 -0.461 1 0 NaN NaN 14.664 1.741 1997 7 17.778 -0.364 0 0 17.778 -0.364 16.130 1.846 1997 8 13.889 -1.571 0 0 13.889 -1.571 12.932 1.331 1997 9 10.000 1.281 0 0 10.000 1.281 8.084 3.224 1997 10 -7.912 -5.367 1 0 NaN NaN -10.035 -3.632 1997 11 -8.444 5.119 0 0 -8.444 5.119 -12.976 4.446 1997 12 -13.885 7.037 1 0 NaN NaN -22.221 2.560 1998 1 -20.500 1.651 0 0 -20.500 1.651 -27.023 -1.013 1998 2 -10.333 7.300 0 0 -10.333 7.300 -16.721 4.771 1998 3 -3.389 7.415 0 0 -3.389 7.415 -8.750 5.913 1998 4 4.833 4.507 0 0 4.833 4.507 2.045 5.578 1998 5 10.333 -0.171 0 0 10.333 -0.171 8.159 1.514 1998 6 13.858 -2.925 1 0 NaN NaN 13.073 0.150 1998 7 NaN NaN NaN NaN NaN NaN 15.630 1.346 1998 8 NaN NaN NaN NaN NaN NaN 10.340 -1.261 1998 9 NaN NaN NaN NaN NaN NaN 6.435 1.575 1998 10 NaN NaN NaN NaN NaN NaN -4.706 1.697 1998 11 NaN NaN NaN NaN NaN NaN -15.599 1.824 1998 12 NaN NaN NaN NaN NaN NaN -22.627 2.154 1999 1 NaN NaN NaN NaN NaN NaN -28.551 -2.541 1999 2 NaN NaN NaN NaN NaN NaN -27.430 -5.938 1999 3 NaN NaN NaN NaN NaN NaN -14.997 -0.334 1999 4 NaN NaN NaN NaN NaN NaN -1.703 1.829 1999 5 NaN NaN NaN NaN NaN NaN 6.181 -0.465 1999 6 NaN NaN NaN NaN NaN NaN 14.510 1.587
