An important distinction between the TRP and simpler traffic metrics is the inclusion of meteorology (average annual wind speed and direction and height of the mixing layer) in addition to proximity and volume.
The air sampling was done at 8 points on both sides of one street that had an average traffic flow, simultaneously meteorology data and vehicle flows were recorded.
The data input for solar radiation model is obtained from the Singapore Meteorological Service (SMS), and these data have been compared with long-term average data of NASA (surface meteorology and solar energy or SSE).
Meteorological data averaged over 22 years (from 1983 to 2005) were extracted as annual averages from the NASA Surface meteorology and Solar Energy Global Data Setss website (www.eosweb.larc.nasa.gov).
These maps were created as a visual tool to assess average spatial patterns before adjusting for meteorology or other predictive variables.
Reason behind the poor performance of HOMER and RetScreen models are use of average of 22-year satellite-measured meteorological data up to the year 2002 from National Aeronautics and Space Administration NASAA) renewable energy resource website (Surface Meteorology and Solar Energy).
Meteorological data, including the average daily temperature (°C), the average daily humidity, and the average daily wind velocity (km/h), were collected from the official website of Shantou Meteorology, TuTiempo.net (http://www.tutiempo.net/en/Climate/Shantou/2011/593160.htm).
This year, a series of heavy storms over the U.S. Midwest to the Northeast have dropped up to 400percentt of average snows in some locations, said Jeff Masters, director of meteorology at Weather Underground.
"For February 3rd through March 4th, Great Falls, MT averaged 32.3F below normal," Sam Lillo, a PhD student in meteorology at the University of Oklahoma, recently tweeted.
Clear skies and dry ground have seen the Alpine nation end the year 3.4C above the long-term historical average for December, a climatologist for the federal office of meteorology and climatology (MeteoSwiss) said on Monday.
