Abstract:
Hydrometeorological analysis forms an important and integral part of hydrological research. One of the important parameters needed for this purpose is the rainfall which itself forms a part of the hydrological cycle.
Rainfall data is collected by a number of organisations. It is a common experience that the rainfall data in its raw form contain many gaps and inconsistent values. As such preliminary processing of this data is essential before it is put to further use in analysis. Processing of the data has two major objectives. One is to evaluate the data for its accuracy and the other is to prepare the data in a most usable form to the users. In earlier times the processing was done manually. The need for use of faster methods of processing the data has been felt with the increase in the number of data records for processing and this led to the use of computers.
The present report is an attempt to compile out the procedures for systematic processing of rainfall data. The concepts of rainfall data processing etc. have been discussed. It provides computer programs which are meant for processing and analysis of rainfall data collected from various sources. Different well documented computer programs, their description with input specifications and test input are given in Appendices.
