If you are using datastream, it will be much more easier. you just need to pick up the start and end dates, then you press the excel sign, the whole period data will be there..

Kamal Ahmed

Thanks for your reply. I checked the functions of Datastream. Datastream mainly works with Economics data. I am dealing with precipitation data.

Once again Thanks

Samuel Toluwalope Ogunjo

Dear Kamal,

I am very much interested in your question but i will like to ask the following questions

(1) What format is the dataset? (2) What programming language do you use?

If you use Matlab, it requires you to use a loop to go through each of the files and evaluate it.

Dear Samuel

Thanks for your interest. I am still looking for a proper solution of this problem.

Format of dataset is netCDF. I was using ArcGIS to extract data for selected latitude and Longitude. I think netCDF file can be open in MatLab but i am not sure . I have attached two files.You can open these files in Notepad and export them to MS Excel and Matlab.

Do you have any code that can extract data in this way?

Regards

Dear Kamal, I would be glad to help out. Just downloaded the files. However, you might have to give me a little time as i have tons of work with several deadlines.

If you do not hear from me by 7th January, 2015 kindly send me a gentle reminder by mail - [email protected].

Thanks for understanding.

Thank you very much. I am really grateful..I understand you are busy. I will remind you.

I am having problem downloading the files. Can you zip the two files?

Sure. I have attached zip file. I am also sending on your email.

Best Regards

Dilip Kumar Gautam

The best way is to use R script with package ncdf, sp, raster and rgdal.

Thanks Dr. I will try to use R scripts.

Warren Luzano

Is there a data beyond 2007?

I hope you managed with R code. You can extract spatially averaged data for a catchment just by giving shape file as mask.

APHRO_MA_025deg_V1101.1951 is this a netcdf file ? it does not open by any standard netcdf reader

O. Burak Akgun

Hi,

I can extract data with R from netcdf file. However, I cannot extract from APHRODITE file with a format like : "APHRO_ME_050deg_V1101.1951". Is there any way to convert this file into ".nc" file or any R package?

Thanks in advance
