***This thread is under modification***
Here are some links to Ocean/Atmosphere datas
__________________________________________________ ________________________
1. IRI/LDEO Climate Data Library : data link
" The IRI/LDEO Climate Data Library contains over 300 datasets from a variety of earth science disciplines and climate-related topics. It is a powerful tool that offers the following capabilities at no cost to the user:"
a). access any number of datasets;
b). create analyses of data ranging from simple averaging to more advanced EOF analyses;
c). monitor present climate conditions with maps and analyses in the Maproom;
d). create visual representations of data, including animations;
e) download data in a variety of commonly-used formats(ASCII,netcdf,etc ....), including GIS-compatible formats.

2. ECMWF Data server : data link
"You will find on this web server data from various projects hosted by ECMWF ( European Centre for Medium-Range Weather Forecasts) " and the datas are available in GRIB or NetCDF formats at surface and different pressure levels, like
a). data from the DEMETER project : several coupled models have been run to produce the hindcasts
b). data from the ECMWF 15 Years Re-Analysis : usually calls it as ERA15 data The ERA-15 production system generated re-analyses from December 1978 to February 1994. The following observations were used:
I. FGGE Level II-B data for 1978/79;
II. COADS ship and buoy observations;
III. ALPEX Level II-B data;
IV. ECMWF archive of observations received via the WMO GTS;
V. additional TEMP and AIREP data from the Japan Meteorological Agency (JMA);
VI. Australian PAOB surface pressure pseudo-observations from Bureau of Meteorology (BoM), Melbourne;
VII. TOGA COARE data;
VIII. TOVS Cloud Cleared Radiance data;
IX. Hadley Centre GISST and NCEP SST analyses.
c). data from the ECMWF 40 Years Re-Analysis : usually calls it as ERA40 data, The new reanalysis project ERA-40 will cover the period from mid-1957 to 2001 including the earlier ECMWF reanalysis ERA-15, 1979-1993, The three dimensional variational technique will be applied using the T159L60 version of the Integrated Forecasting System to produce the analyses every six hours. Analysis involves comprehensive use of satellite data, starting from the early Vertical Temperature Profile Radiometer data in 1972, then later including TOVS, SSM/I, ERS and ATOVS data. Cloud Motion Winds will be used from 1979 onwards.
d). ENACT data (in development) :
e) Atlantic THORPEX Regional Campaign (A-TreC) dataset : The Atlantic THORPEX Regional Campaign (A-TreC) data sets have been created according to the A-TreC SOP Observation Matrix - Version 3 updated 23rd of March 2004. The SOP took place from 17/10/2003 to 15/12/2003. During the Special Observing Period (SOP) in addition to the standard WMO observing system the additional drop sondes, land based radio sondes, high frequency AMDAR reports, radiosondes from ASAP ships and rapid-scan winds from geostationary satellites were available. The data are organized by calendar date in 24 hour slots.

4. SeaWiFS Data Access : data link
"This data set consists of satellite measurements of global and regional Earth radiance data obtained by SeaWiFS on the OrbView-2 (formerly SeaStar) platform."
it includes various parametrs like Chlorophyll_a concentration, Aerosol optical thickness, Water leaving Radiance, etc.. and related products, all SeaWiFS data are in Hierarchical Data Format (HDF) format.
For getting this data you should register in this site and u will get an Id and password for data acces.
This site provides spatial and temporal selection utility for downloading the datas

5. MODIS-Terra Data Products : data link
"This data set consists of Radiances and Geolocations, Atmosphere and Ocean data products derived from observations made by the MODIS instrument on board the Terra (EOS AM-1) satellite. Most of the files are in HDF-EOS format, while some others are in HDF4 format". Thier product list is big, so i can't include all in this thread, just go through the site

6. MODIS-Aqua Data Products : data link
"This data set consists of Radiances and Geolocations, Atmosphere and Ocean data products derived from observations made by the MODIS instrument on board the Aqua satellite. Most of the files are in HDF-EOS format, while some others are in HDF4 format". Thier product list is big, so i can't include all in this thread, just go through the site"

8. Simple Ocean Data Assimilation Project (SODA). data link
Contributed by vinu
SODA_1.2 is UMD reanalysis product using an eddy-permitting global model based initially on POP_1.3 numerics and SODA procedure. The details please see here.
The horizontal resolution of POP on the equator is 28km x 44km reducing to an approximately uniform 25km x 25 km in the weatern North Atlantic. Vertically, it contains 40 levels, from ocean surface to about 5500m. The OI analysis was done with our SODA procedure every 10 day on 1 by 1 degree resulotion. The observation data of sst, temperature and salinity were used in the analysis. Altimetry data were not used in this product.
The datasets we provided are on a 0.5 x 0.5 degree horizontal resolution with 23 levels, from 5m to 1139m. The variables in the datasets are: temperature, salinity, zonal & meridional velocities, windstresses, sea surface height, heat & fresh water fluxes. The time coverage is monthly, from 1958 to 2001.

10. British Atmospheric Data Center. data link
contributed by vinu
The British Atmospheric Data Centre (BADC) is the Natural Environment Research Council's (NERC) Designated Data Centre for the Atmospheric Sciences. Access to the data is limited and will be permitted on the written request sent to the UKMO [UK Met Office].
For details see here . ECMWF is one of the data sets provided by UKMO with public access meant for the academic purposes. GSST (Global Ocean Surface Temperature Atlas) is a montly mean observed SST spanning more than 100 years. ( see details here). Other data sets of various Ocean/Atmophseric parameters are also available.
