Abstract VLBI observations at various stations all over the globe have been carried out since the beginning of the eighties. As VLBI allows to determine tropospheric parameters such as hydrostatic and wet zenith path delays stable and long time series of these parameters exist that can be used for climatological studies. From the wet zenith delays information about trends and periodic variations of the amount of water vapour in the troposphere can be obtained. For example a trend of ∼ +0.7 mm/year in the wet zenith delay will correspond to a trend of ∼ +0.1 mm/year in precipitable water. For assessing the reliability of the linear trends and the amplitudes of annual and semiannual components, data from VLBI, GPS, and the ECMWF (European Centre for Medium-Range Weather Forecasts) were compared. Good agreement was found for the seasonal variations, though the linear trends showed some disagreement. Possible reasons for this disagreement are discussed. Finally, the effect of El Nino events on tropospheric mapping functions and on length-of-day time series is shown.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
