[gradsusr] Request of help to explore IMD rainfall dataset.

[SINHA P.N.]

Hi,

I am totally new to GrADS and don't really know whether it will solve my purpose or not. However thought to write and ask if it could be of any help.

My problem is - I need to do rainfall analysis for my study area which falls within 21.25- 23.75 N latitude and 83.75-86.75 E longitude. I have Indian Metrological Department (IMD) rainfall data for 1971-2005 at 0.5 degree resolution. My study area covers 25 cells (0.5 deg) of this dataset. In my research, I want to understand the hydrological behaviour of my catchments. For that, I want to do some simple statistical analysis using daily rainfall data (1971-2005) for my study area. However, as some of you know, this data is in 'grd format' thus it cannot be directly used in excel. I need to convert this data in text/ascii or any other format which can be opened in excel. I am very new to such type of work thus completely helpless to convert it in some usable format. While searching on internet, I came to know about this forum. So, I thought to write here and check -


1.       Is it the right platform which can help me in this problem?

2.       If yes, is there anyone who can help me in it? (I will highly appreciate any help in this regard! Even, simple guidelines  would help me to explore further. Using the guidelines available I could only convert 'grd format' into 'prt format' however I am unable to move forward.)


Just for information, I acquired data from my university and it was purchased by university for the project of one student. However, the student already completed his PhD and left.  I tried to contact but could not reach him. I also tried to explore some other avenues but could not find any solution for my problem. So I just thought to share my problem in this forum.

Any help will be much appreciated.


With regards,
P Sinha
