There are a lot of online website that offers free environmental data like rainfall, temp etc. Just google for such sites as MODIS. However, if you are willing to pay, sites like quickbird, spot satelites from france can send you these information for a fee.

You can always use the WorldClim dataset (http://www.worldclim.org). It is a gridded global dataset resolved to about a kilometer. It contains many summarized (min, max, man temps and rainfall) and calculated, biologically relevant variables for past, current, and future conditions. These data are used by many for species distribution models. If these data are not sufficient, then you'll need to search databases through NCDC, NOAA, or NASA )among others).

Hello Vaijayanti!! Along with the above suggestions, you can also check in http://www.ipcc-data.org/ , http://www.climatus.com/index.php , http://www.ncdc.noaa.gov/sotc/global/2012/10,

It depends on what resolution do you require the data which again depend on the purpose of your requirement. Be careful in selecting the data sets!!

All the best.

you can also find the long term climate data sets from MERRA GEovannii site which provide you all the inputs required for any empirical or processed based models.

@ Vaijayanti I give you this link where you can freely download the CC data but can also explore research centers where they can give you this information. The question I have is that the data that you want to do. http://ipcc.ch/publications_and_data/publications_and_data_reports.shtml#.US9h5Dfoixk

Hy, u can download this data from www.lapig.iesa.ufg.br

@ Vaijayanti I give you this other link Here you can search the environment section and you can find scientific articles on the subject http://ageconsearch.umn.edu/

@ Philip Hanke

The website you have referred me to provides data in the SWAT file format. How may I conver it to GeoTIFF?

Data from the http://www.ncdc.noaa.gov/sotc/global/2012/10 gives data in the .nc format. how do i convert it to geotiff?

Thank you all Also pl visit website of my institute for Conference at my institute. www.sinhgad.edu click on Lonavla

Dear you can to download here: http://www.ieham.org/html/docs/documentacion2.asp?cat=19&val=1&lengua=1

Dear you can download from these site

Take a look at the Global Summary of the Day (GSOD):

http://www.ncdc.noaa.gov/cgi-bin/res40.pl?page=gsod.html

Dear take a look at the FAO web site where you will find information smart agricultural climate http://www.fao.org/climatechange/climatesmart/en/

You can download daily meteorological data from here: http://www.climatic-maps.org/daily-data

we can download NASA physical oceanography division.

And here is how to use the in ArcGIS https://sites.google.com/site/vincenzoaellis/arcgis-notes

I like the Global Summary of the Day (GSOD), because it's raw data (data not manipulated by gridding). Contains temperature, precipitation, wind, atmospheric pressure, and other variables.

Look here: http://catalog.data.gov/dataset/global-surface-summary-of-the-day-gsod

Dear Vaijayanti I recommend you this link http://www.ipcc-nggip.iges.or.jp/software/index.html for Smart Agriculturral Climate. It is well for inventory in climate change may be usefull for you. I know that it not your questions, but I think it can be usefull.

i need future climate for my study area of punjab but i m not able to get the proper data i consulted all the weather generator  sites, but not please help me by providing the appropriate site

Dear you can visit the FAO web site, where you can to find data base. So The data are organized in Agricultural Smarth Climate  http://faostat3.fao.org/browse/G1/*/E  and http://faostat3.fao.org/search/agricultura%20climaticamente%20inteligente/E

Dear I recomend you visit our web Journal http://revista.unanleon.edu.ni/index.php/REBICAMCLI/index It you can to find some documents where you to can review the source and data base.

Carlos

 Dear Vaijayanti,

There is a good site where you can download up to date climate data such as precipitation, Average minimum maximum temperature, relative humidity, wind speed, global radiation..etc.

see the following site:

http://power.larc.nasa.gov/cgi-bin/[email protected]

Best regards 

Worldclim (http://www.worldclim.org/) has 30-year averages, spatially downscaled (30 arc second) temp, precip and bioclimatic variables. These are good for habitat suitability mapping.

NASA Earth Exchange (NEX) provides downscaled climate projections (30 arc second) temp and precip, monthly from 1950 to 2099. (https://cds.nccs.nasa.gov/nex/) 

Hi

You can open my website: http://agrimetsoft.com and in bellow there is many link to gridded data such as AgMerra, PERSIANN, and etc....

i think AgMerra is good for you

Cheers

You can try whith this link: https://climexp.knmi.nl/selectstation.cgi?id=someone@somewhere,

It is also highly recomended the https://theclimatedatafactory.com/ ,

with climate projections data over 4,300 cities and 70 countries worldwide.

Good luck

Hi, you can use this link

https://clim-engine-development.appspot.com/fewsNet

It's very useful, friendly user and covers all world.

PERSIANN global satellite precipitation data, PERSIANN-Cloud Classification System (CCS), and PERSIANN-Climate Data Record (CDR), available from the CHRS Data Portal (https://chrsdata.eng.uci.edu ).

This is other posibility you can use https://www.globalclimatemonitor.org/#

I think it'll help

http://www.worldclim.org

IBM has this data as well. I think it's free for some researchers (maybe just students). Check out their new analytics (not just called Watson anymore apparently)

You can try Meteonorm:

https://meteonorm.com/

Just an Update, you can try to use also: http://www.cru.uea.ac.uk/data

https://www.globalclimatemonitor.org/

I think you can download from different data set one is from esrl noaa lab , merra dataset nasa or you can download from jma reanalysis dataset.

GPCP

CMORPH

PERSIANNN

Where can I download data on kidney failure?

Can you try with this :

https://power.larc.nasa.gov/data-access-viewer/

I will suggest you

KNMI -The Royal Netherlands Meteorological Institute and-

NCDC -National Centers for Environmental Information-
