% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 167188 % Primary Name: WALLER BWI % Record Type: TAVG % Country: Trinidad and Tobago % State: ZZ % Latitude: 10.61670 +/- 0.00005 % Longitude: -61.21670 +/- 0.00005 % Elevation (m): 41.10 +/- 0.05 % # of Months: 12 % % IDs: ghcnd - TDW00011610 % gsod - 999999-11610 % ncdc - 20030023 % wban - 11610 % % Sources: US First Order Summary of the Day % Global Historical Climatology Network - Daily % Global Summary of the Day % Multi-network Metadata System % % Site Hash: 3e2c53ae5309afcd364c185c9ebba83c % Raw Data Hash: b9387d80fe349b62ae9be3a6c874c4f0 % Adj Data Hash: 3dd2133e03a75a769bed6988dd143d90 % % 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 1948 1 NaN NaN NaN NaN NaN NaN 25.092 -0.205 1948 2 NaN NaN NaN NaN NaN NaN 25.431 -0.121 1948 3 NaN NaN NaN NaN NaN NaN 25.876 -0.364 1948 4 NaN NaN NaN NaN NaN NaN 25.742 -1.053 1948 5 NaN NaN NaN NaN NaN NaN 27.343 0.144 1948 6 NaN NaN NaN NaN NaN NaN 26.354 -0.215 1948 7 NaN NaN NaN NaN NaN NaN 26.104 -0.248 1948 8 NaN NaN NaN NaN NaN NaN 26.241 -0.320 1948 9 NaN NaN NaN NaN NaN NaN 26.517 -0.272 1948 10 NaN NaN NaN NaN NaN NaN 26.435 -0.168 1948 11 NaN NaN NaN NaN NaN NaN 26.331 -0.004 1948 12 NaN NaN NaN NaN NaN NaN 25.266 -0.320 1949 1 23.342 -1.641 0 0 23.342 -1.641 24.530 -0.767 1949 2 24.373 -0.866 1 0 NaN NaN 25.228 -0.325 1949 3 24.866 -1.060 0 0 24.866 -1.060 25.926 -0.313 1949 4 25.583 -0.898 0 0 25.583 -0.898 26.410 -0.385 1949 5 26.126 -0.759 0 0 26.126 -0.759 27.075 -0.124 1949 6 26.280 0.024 0 0 26.280 0.024 26.220 -0.350 1949 7 26.503 0.464 0 0 26.503 0.464 26.230 -0.122 1949 8 26.311 0.064 0 0 26.311 0.064 26.139 -0.423 1949 9 26.702 0.226 0 0 26.702 0.226 26.555 -0.234 1949 10 26.671 0.382 0 0 26.671 0.382 26.443 -0.160 1949 11 26.357 0.336 0 0 26.357 0.336 26.353 0.018 1949 12 25.030 -0.241 1 0 NaN NaN 25.199 -0.386 1950 1 NaN NaN NaN NaN NaN NaN 24.695 -0.602 1950 2 NaN NaN NaN NaN NaN NaN 25.237 -0.315 1950 3 NaN NaN NaN NaN NaN NaN 25.308 -0.932 1950 4 NaN NaN NaN NaN NaN NaN 25.952 -0.843 1950 5 NaN NaN NaN NaN NaN NaN 26.503 -0.696 1950 6 NaN NaN NaN NaN NaN NaN 25.932 -0.638 1950 7 NaN NaN NaN NaN NaN NaN 26.066 -0.286 1950 8 NaN NaN NaN NaN NaN NaN 25.968 -0.593 1950 9 NaN NaN NaN NaN NaN NaN 26.697 -0.092 1950 10 NaN NaN NaN NaN NaN NaN 26.510 -0.092 1950 11 NaN NaN NaN NaN NaN NaN 26.340 0.005 1950 12 NaN NaN NaN NaN NaN NaN 25.583 -0.003
