For our educational and research work, the Environmental Central Facility (ENVF) of Institute for the Environment, the Hong Kong University of Science and Technology (HKUST) gathers and archives atmospheric and environmental data / information available on the internet.
Atmospheric and environmental data come from many different sources and in different formats. Typically, it takes a long time for our researchers or students to be familiar with a few data types. Even then, it will still be very time-consuming for them to gather and decode all the data available for their specific research or educational objectives. These make it difficult for them to develop an overall perspective that is very important for a deeper understanding of atmospheric and environmental interactions.
Hence, an atmospheric and environmental database have been developed with an expert plotting / data query interface to allow our researchers and students easy and efficient access to most of the archived information, skipping the initial difficulties of data collection and decoding. As the primary objective of this system is to assist our researchers and students in their research and academic work, our database system and our plotting / data query interfaces are under constant modifications / upgrades. Errors, both systematic and random, will occur and we appreciate any effort for pointing out such errors. Any other suggestions for improving our system are also welcomed. Please send your suggestions to firstname.lastname@example.org or fax them to (852)-2358-1582.

Global Telecommunication System (GTS) is part of the
World Weather Watch
Program of the World Meteorological Organization
(WMO). The system consists of integrated networks of telecommunications
facilities and services for the rapid, reliable collection and distribution
of observational data and processed information. The bulk of the atmospheric
data in our atmospheric and environmental database are recorded observations
available on the GTS network.
This page is mainly based on hourly aviation weather reports (METAR) available on the GTS network. There are six plots on this page, including Temperature, Dew Point, Wind Speed, Wind Direction, Sea Level Pressure and Visibility. These plots are updated once every hour.
This page is mainly based on surface weather information (SYNOP) available on the GTS network. There are eight plots on this page, including Precipitation, Temperature, Dew Point, Sea Level Pressure, Wind Speed, Wind Direction, Relative Humidity and Visibility. These plots are updated once every three hours.
This page is for making spatial (latitude-longitude) plots of selected atmospheric and environmental parameters. The atmospheric and environmental parameters are classfied into five catagories, namely (1) Hourly Meteorological Data, (2) Upper-level Meteorological Data, (3) Daily Meteorological Data, (4) Monthly Meteorological data and (5) Air Quality Data.
This page is for making vertical sounding plots at selected times and locations.
