Data access

1. Data portal
   The simplest way how to get rather smaller ad hoc data samples (approximately up-to 20 000 retrieved fields per request)  
2. Batch access
   The ECMWF access in batch should be used for most common types of work (big data samples retrievals)
3. CMA data portal
   2nd official S2S data portal where all data from all partners can be downloaded.

Data  monitoring

• History page
  The data gaps caused by any kind of problems can be checked via the so-called S2S history web page.

GRIB2 and NETCDF conversion

• GRIB-API
  ECMWF has developed a C GRIB API for encoding, decoding and data manipulation in GRIB-2 format. All TIGGE parameters should be recognized through GRIB_API.
• grib2_to_netcdf
  grib2_to_netcdf is an NCAR  conversion utility built on the ECMWF GRIB_API and Unidata NetCDF libraries. The utility converts regular lat/lon gridded S2S data from GRIB-2 to NetCDF format.

Other External tools

• S2S Museum
  The museum includes a set of scripts to download TIGGE data, and plot it (using GrADS ) in file TIGGE_sample.tar.gz - available directly from here.
