The Indian rainfall data set was derived from 306 almost uniformly distributed stations for which rainfall data are available from 1871. The hilly regions consisting of four meteorological subdivisions of India which are parallel to Himalayan mountain range have not been considered in view of the meagre ... rain-gauge network and low areal representation of a rain-gauge in a hilly area. Two island subdivisions far away from mainland have also not been included. Thus, the contiguous area having network of 306 stations over 30 meteorological subdivisions measures about 2,880,000 sq.km., which is about 90 percent of the total area of the country.
The monthly (January - December) area weighted rainfall series for each of the 30 meteorological subdivisions have been prepared by assigning the district area as the weight for each rain-gauge station in that subdivision. Similarly assigning the subdivision area as the weight to each of the subdivisions in the region, area weighted monthly rainfall series are prepared for Homogeneous regions of India as well as for all India.
The data for the recent period 1991-2003 are preliminary estimates based on the subdivisional means supplied by the India Meteorlogical Department (IMD), which are in turn based on a variable network. However, the IMD data have been rescaled to conform to the long-term means of the respective subdivisions in the IITM-IMR data set. These data will be updated as and when the full set of data for 306 stations becomes available.
Description:
The GeoConnections Discovery Portal, formerly the Canadian Earth Observation Network (CEONet), is where Canadians and others interested in Canadian geospatial data have been coming since 1997 to discover, evaluate and access geospatial data products and services. The GeoConnections Discovery Portal provides infrastructure tools and services to serve a wide range of Canadian stakeholders. It is offered free for any organization or individual to use. Registering and advertising, having your geospatial data remotely searched, as well as having access to free software tools and Internet-accessible services are indeed bonuses. Technical help and support are also available free of charge. These are important considerations when looking for a data discovery solution for your organization. The Discovery Portal is ideally suited for geospatial data discovery with it geographic focus, fielded searches and library like functionality.
Description:
GeoConnections will: develop the Canadian Geospatial Data Infrastructure (CGDI), which will coordinate Canada?s numerous databases of geographic information and make them accessible through a common window on the Internet; and enable partnerships between federal, provincial and territorial governments, the private sector and the academic community.
