Sentences with phrase «station observations»

The forecasts were verified with road weather station observations.

Each individual stations observation is put into graphical format so that it is simple to understand, can be put on a chart and be compared to its neighbours.

The CRMP agreement which also has Environment Canada support, provides PCIC with station observations from more than 6,000 sites across the province of BC.

By analyzing surface station observations and the Climate Forecast System (CFS) Reanalyses (CFSR), as well as the NCEP CFS version 2 (CFSv2) reforecast data over 18 summers from 1993 to 2010, it was found that the QBW mode plays a significant role in the formation of episodic diurnal convection.

Lastly, there is no mention (at least, I could not find it) of how NCEP / NCAR grid point data was interpolated to station locations and station observation time (the gridded data is available only 4 times daily and how the author makes these times match is rather critical).

In the most realistic case of half - field capacity, the July daily minimum temperature in the California Central Valley increased by 3.5 °C, in agreement with station observation trends over the past century in the same area.

Near - surface air temperatures and 500 - hPa temperatures over Antarctica for 1960 — 2007 have been reconstructed over the entire continent using manned station observations and radiosonde records, respectively, from the READER database maintained by British Antarctic Survey.

The method combines the results of long - term atmospheric reanalyses downscaled with a stochastic statistical method and homogenized station observations to derive the meteorological forcing needed for hydrological modeling.

In a 30 - yr historical evaluation period, Climdex indices computed from 800 - m simulated values display reduced error relative to local station observations than those from the 10 - km dataset, with the greatest reduction in error occurring at high - elevation sites for precipitation - based indices.

These indices are also calculated from weather station observations recorded at 22 locations within southwestern British Columbia, Canada, to evaluate the performance of both the 10 - km and 800 - m datasets in replicating the observed quantities.

forecast lead - time at which the continuous ranked probability skill score (CRPSS) for ENS probabilistic forecasts of 24 - hour total precipitation reaches 10 % for the extra-tropics (northern and southern hemispheres); verification against station observations

Opportunities for the incorporation of bias and errors into the satellite data sets and the Comprehensive Ocean Atmosphere Data Set (COADS) relied upon by the IPCC and NOAA begin with the methods used to average the raw data observations from sea station observations in the VOS network into one and five degree regions.

The exact amount of estimated warming depends upon which of the existing compilations of the data is used as a basis for the calculation, the method used to estimate global means on the basis of irregularly spaced station observations, and the way in which the data are smoothed in time.

PCIC provides station observations of weather and climate variables (such as temperature and rainfall amounts) in British Columbia, from 1870 to the present day.

The comparison of the reanalysis with the unadjusted and adjusted station data indicates that the reanalysis can be used to detect the inhomogeneity of individual station observations resulting from nonclimatic biases.

To submit station observations, please submit your observations to NOAA's National Climatic Data Center [email protected] using the ASCII exchange format v1.0.

Lastly, there is no mention (at least, I could not find it) of how NCEP / NCAR grid point data was interpolated to station locations and station observation time (the gridded data is available only 4 times daily and how the author makes these times match is rather critical).

By analyzing surface station observations and the Climate Forecast System (CFS) Reanalyses...

PRISM Climate Group, Oregon State University Oregon State University's PRISM Climate Group develop spatial climate datasets, which include precipitation, vapour pressure and temperature variables, using weather station observations and detailed methods that incorporate knowledge of the region, including expert assessments.

Another source of information related to observation - based data sets are reanalysis data sets in which numerical model forecasts and weather station observations are combined into a single gridded reconstruction of climate over the globe.

The GISTEMP analysis uses linear weights that decrease as a function of distance from a station observation.
