% This file contains a station summary listing for a temperature % station in the Berkeley Earth database. This station is identified as: % % Berkeley ID#: 23946 % Primary Name: IMPERIAL COL % Record Type: TAVG % Country: Trinidad and Tobago % Latitude: 10.63000 +/- 0.00500 % Longitude: -61.40000 +/- 0.00500 % Elevation (m): 16.00 +/- 0.50 % # of Months: 60 % % IDs: ca - 424000000002 % % Sources: Colonial Archive % % Site Hash: b4a69ab14b4dc664286bb799e7998b2d % Raw Data Hash: 6a30f346eac4c23494d4343ecf86341e % Adj Data Hash: a7a75225badc923347e73216d71ca478 % % 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 1951 1 NaN NaN NaN NaN NaN NaN 24.745 -0.552 1951 2 NaN NaN NaN NaN NaN NaN 25.335 -0.217 1951 3 NaN NaN NaN NaN NaN NaN 25.891 -0.349 1951 4 NaN NaN NaN NaN NaN NaN 26.630 -0.166 1951 5 NaN NaN NaN NaN NaN NaN 27.121 -0.078 1951 6 NaN NaN NaN NaN NaN NaN 26.236 -0.333 1951 7 NaN NaN NaN NaN NaN NaN 26.322 -0.030 1951 8 NaN NaN NaN NaN NaN NaN 26.625 0.063 1951 9 NaN NaN NaN NaN NaN NaN 26.748 -0.041 1951 10 NaN NaN NaN NaN NaN NaN 26.412 -0.191 1951 11 NaN NaN NaN NaN NaN NaN 26.180 -0.155 1951 12 NaN NaN NaN NaN NaN NaN 25.708 0.123 1952 1 25.050 -0.052 0 0 25.050 -0.052 25.322 0.025 1952 2 25.050 -0.308 0 0 25.050 -0.308 25.765 0.213 1952 3 26.050 0.005 1 0 NaN NaN 26.596 0.356 1952 4 27.250 0.649 0 0 27.250 0.649 27.368 0.572 1952 5 27.150 0.146 0 0 27.150 0.146 27.754 0.555 1952 6 26.550 0.175 0 0 26.550 0.175 26.541 -0.028 1952 7 26.200 0.042 0 0 26.200 0.042 26.333 -0.020 1952 8 26.400 0.034 0 0 26.400 0.034 26.412 -0.149 1952 9 26.850 0.256 0 0 26.850 0.256 26.814 0.024 1952 10 26.850 0.442 0 0 26.850 0.442 26.755 0.152 1952 11 26.150 0.010 0 0 26.150 0.010 26.277 -0.058 1952 12 25.300 -0.090 0 0 25.300 -0.090 25.424 -0.162 1953 1 25.250 0.148 0 0 25.250 0.148 25.297 0.000 1953 2 24.750 -0.608 0 0 24.750 -0.608 25.338 -0.214 1953 3 25.450 -0.595 0 0 25.450 -0.595 25.996 -0.244 1953 4 26.700 0.099 0 0 26.700 0.099 26.999 0.204 1953 5 26.550 -0.454 0 0 26.550 -0.454 26.832 -0.367 1953 6 26.250 -0.125 0 0 26.250 -0.125 26.572 0.003 1953 7 26.300 0.142 0 0 26.300 0.142 26.444 0.091 1953 8 26.350 -0.016 0 0 26.350 -0.016 26.614 0.053 1953 9 26.600 0.006 0 0 26.600 0.006 26.813 0.023 1953 10 26.400 -0.008 0 0 26.400 -0.008 26.553 -0.050 1953 11 26.250 0.110 0 0 26.250 0.110 26.536 0.201 1953 12 25.600 0.210 0 0 25.600 0.210 25.732 0.146 1954 1 24.750 -0.352 0 0 24.750 -0.352 25.145 -0.152 1954 2 24.650 -0.708 0 0 24.650 -0.708 25.372 -0.181 1954 3 25.450 -0.595 0 0 25.450 -0.595 25.919 -0.320 1954 4 26.050 -0.551 0 0 26.050 -0.551 26.213 -0.582 1954 5 26.950 -0.054 0 0 26.950 -0.054 27.114 -0.085 1954 6 26.550 0.175 0 0 26.550 0.175 26.402 -0.168 1954 7 26.000 -0.158 0 0 26.000 -0.158 26.073 -0.280 1954 8 26.300 -0.066 0 0 26.300 -0.066 26.287 -0.274 1954 9 26.600 0.006 0 0 26.600 0.006 26.491 -0.298 1954 10 25.950 -0.458 0 0 25.950 -0.458 25.895 -0.708 1954 11 25.550 -0.590 0 0 25.550 -0.590 25.736 -0.599 1954 12 25.050 -0.340 0 0 25.050 -0.340 25.111 -0.475 1955 1 24.550 -0.552 0 0 24.550 -0.552 24.878 -0.419 1955 2 24.950 -0.408 0 0 24.950 -0.408 25.479 -0.073 1955 3 25.500 -0.545 0 0 25.500 -0.545 25.682 -0.558 1955 4 26.350 -0.251 0 0 26.350 -0.251 26.240 -0.556 1955 5 26.950 -0.054 0 0 26.950 -0.054 27.183 -0.016 1955 6 26.150 -0.225 0 0 26.150 -0.225 26.254 -0.316 1955 7 26.050 -0.108 0 0 26.050 -0.108 26.340 -0.013 1955 8 26.500 0.134 0 0 26.500 0.134 26.863 0.301 1955 9 26.200 -0.394 0 0 26.200 -0.394 26.314 -0.475 1955 10 26.600 0.192 0 0 26.600 0.192 26.565 -0.038 1955 11 26.050 -0.090 0 0 26.050 -0.090 26.278 -0.057 1955 12 25.150 -0.240 0 0 25.150 -0.240 25.407 -0.178 1956 1 25.300 0.198 0 0 25.300 0.198 25.452 0.155 1956 2 24.850 -0.508 0 0 24.850 -0.508 25.341 -0.212 1956 3 25.650 -0.395 0 0 25.650 -0.395 25.902 -0.338 1956 4 26.050 -0.551 0 0 26.050 -0.551 26.458 -0.338 1956 5 26.500 -0.504 0 0 26.500 -0.504 26.702 -0.497 1956 6 26.000 -0.375 0 0 26.000 -0.375 26.200 -0.370 1956 7 26.150 -0.008 0 0 26.150 -0.008 26.332 -0.020 1956 8 26.200 -0.166 0 0 26.200 -0.166 26.253 -0.308 1956 9 26.100 -0.494 0 0 26.100 -0.494 26.252 -0.537 1956 10 26.300 -0.108 0 0 26.300 -0.108 26.220 -0.383 1956 11 26.100 -0.040 0 0 26.100 -0.040 26.176 -0.159 1956 12 25.350 -0.040 0 0 25.350 -0.040 25.127 -0.458 1957 1 NaN NaN NaN NaN NaN NaN 24.694 -0.603 1957 2 NaN NaN NaN NaN NaN NaN 25.150 -0.402 1957 3 NaN NaN NaN NaN NaN NaN 25.944 -0.296 1957 4 NaN NaN NaN NaN NaN NaN 26.200 -0.595 1957 5 NaN NaN NaN NaN NaN NaN 26.728 -0.471 1957 6 NaN NaN NaN NaN NaN NaN 26.516 -0.054 1957 7 NaN NaN NaN NaN NaN NaN 26.482 0.129 1957 8 NaN NaN NaN NaN NaN NaN 26.783 0.222 1957 9 NaN NaN NaN NaN NaN NaN 27.222 0.433 1957 10 NaN NaN NaN NaN NaN NaN 27.177 0.574 1957 11 NaN NaN NaN NaN NaN NaN 26.474 0.139 1957 12 NaN NaN NaN NaN NaN NaN 25.570 -0.015
