% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 4336 % Primary Name: PERTH AIRPORT COMPARISON % Record Type: TAVG % Country: Australia % Latitude: -31.93560 +/- 0.00005 % Longitude: 115.96390 +/- 0.00005 % Elevation (m): 20.00 +/- 0.50 % # of Months: 34 % % IDs: ghcnd - ASN00009250 % % Sources: Global Historical Climatology Network - Daily % % Site Hash: 98ebc33f0badee6955ef47f30eda172e % Raw Data Hash: 11bee18431ef186588b850b75eaa76af % Adj Data Hash: 4875df96c5b6a641a66a9854c46f9983 % % 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 11 NaN NaN NaN NaN NaN NaN 21.061 0.989 1996 12 NaN NaN NaN NaN NaN NaN 22.557 -0.937 1997 1 NaN NaN NaN NaN NaN NaN 27.305 1.573 1997 2 NaN NaN NaN NaN NaN NaN 27.020 1.521 1997 3 NaN NaN NaN NaN NaN NaN 22.708 -0.486 1997 4 NaN NaN NaN NaN NaN NaN 19.849 1.403 1997 5 NaN NaN NaN NaN NaN NaN 14.712 0.024 1997 6 NaN NaN NaN NaN NaN NaN 13.636 1.378 1997 7 NaN NaN NaN NaN NaN NaN 10.555 -0.569 1997 8 NaN NaN NaN NaN NaN NaN 11.240 -0.165 1997 9 NaN NaN NaN NaN NaN NaN 13.763 0.453 1997 10 NaN NaN NaN NaN NaN NaN 17.237 1.032 1997 11 19.402 -1.144 1 0 NaN NaN 19.630 -0.443 1997 12 24.710 0.741 0 0 24.710 0.741 24.972 1.477 1998 1 26.072 -0.134 1 0 NaN NaN 26.725 0.993 1998 2 25.336 -0.636 1 0 NaN NaN 26.304 0.805 1998 3 NaN NaN NaN NaN NaN NaN 24.766 1.572 1998 4 20.717 1.797 0 0 20.717 1.797 18.961 0.515 1998 5 19.081 3.918 0 0 19.081 3.918 17.303 2.614 1998 6 14.304 1.572 0 0 14.304 1.572 12.192 -0.066 1998 7 NaN NaN NaN NaN NaN NaN 10.118 -1.007 1998 8 15.808 3.929 1 0 NaN NaN 13.351 1.946 1998 9 NaN NaN NaN NaN NaN NaN 12.771 -0.540 1998 10 16.607 -0.072 0 0 16.607 -0.072 16.582 0.377 1998 11 19.846 -0.700 0 0 19.846 -0.700 20.981 0.908 1998 12 22.483 -1.486 0 0 22.483 -1.486 24.025 0.530 1999 1 23.068 -3.138 1 0 NaN NaN 26.392 0.660 1999 2 25.739 -0.234 1 0 NaN NaN 26.644 1.146 1999 3 23.096 -0.572 1 0 NaN NaN 23.044 -0.150 1999 4 22.292 3.372 1 0 NaN NaN 20.341 1.896 1999 5 NaN NaN NaN NaN NaN NaN 16.221 1.533 1999 6 13.780 1.047 0 0 13.780 1.047 12.826 0.567 1999 7 13.962 2.363 0 0 13.962 2.363 11.971 0.846 1999 8 13.250 1.371 0 0 13.250 1.371 11.621 0.217 1999 9 13.926 0.141 0 0 13.926 0.141 13.415 0.105 1999 10 16.245 -0.433 0 0 16.245 -0.433 15.969 -0.235 1999 11 20.461 -0.086 0 0 20.461 -0.086 21.078 1.006 1999 12 24.125 0.156 0 0 24.125 0.156 24.932 1.437 2000 1 24.214 -1.992 0 0 24.214 -1.992 24.642 -1.090 2000 2 24.240 -1.733 0 0 24.240 -1.733 25.505 0.007 2000 3 22.575 -1.094 0 0 22.575 -1.094 22.717 -0.477 2000 4 19.922 1.002 0 0 19.922 1.002 18.749 0.303 2000 5 NaN NaN NaN NaN NaN NaN 14.120 -0.568 2000 6 14.607 1.875 0 0 14.607 1.875 13.252 0.994 2000 7 13.615 2.016 0 0 13.615 2.016 12.204 1.079 2000 8 12.683 0.805 0 0 12.683 0.805 11.072 -0.333 2000 9 15.800 2.015 0 0 15.800 2.015 14.637 1.327 2000 10 17.241 0.563 1 0 NaN NaN 17.346 1.142 2000 11 20.214 -0.332 0 0 20.214 -0.332 20.853 0.781 2000 12 23.750 -0.219 1 0 NaN NaN 25.150 1.655 2001 1 22.533 -3.673 1 0 NaN NaN 26.386 0.654 2001 2 NaN NaN NaN NaN NaN NaN 24.293 -1.205 2001 3 NaN NaN NaN NaN NaN NaN 22.538 -0.656 2001 4 NaN NaN NaN NaN NaN NaN 19.951 1.505 2001 5 NaN NaN NaN NaN NaN NaN 15.379 0.691 2001 6 NaN NaN NaN NaN NaN NaN 12.467 0.209 2001 7 NaN NaN NaN NaN NaN NaN 11.195 0.070 2001 8 NaN NaN NaN NaN NaN NaN 11.253 -0.151 2001 9 NaN NaN NaN NaN NaN NaN 13.501 0.191 2001 10 NaN NaN NaN NaN NaN NaN 15.572 -0.632 2001 11 NaN NaN NaN NaN NaN NaN 20.891 0.818 2001 12 NaN NaN NaN NaN NaN NaN 21.695 -1.800 2002 1 NaN NaN NaN NaN NaN NaN 25.417 -0.315
