How to write my first Web-API script?

...

Public users

You may start with the examples available on ERA-interim TIGGE sample scripts or by creating your request using our Datasets Web Interface . Please note the following:

1. We strongly advice you to start with a simple request. ( 1-2 parameters 1 time step 1-2  steps etc)
2. In case of Python the request will be a dictionary with "keys" and "values" that represent your selection. (eg "step":"00", "time": 00")
3. The request is strongly connected to the availability of the data
4. The request has a Python dictionary format.
5. You can use the Use the example below as a basis to write your own script

 #!/usr/bin/env python
from ecmwfapi import ECMWFDataServer
    
server = ECMWFDataServer()
    

server.retrieve({
    'origin' 
   : "stream"kwbc",
    'levelist'  : "oper200",
    "'levtype"'   : "sfcpl",
    'expver'    "param": "165.128/41.128prod",
    "'dataset"'   : "interimtigge",
    "step":'step'      : "0/6",
    "grid"'grid'      : "0.755/0.755",
    'param'     : "131/132",
    'time'      : "00/06/12/18",
    'date'      : "002014-10-01",
    'type'      : "cf",
    'class'     : "dateti",
    'target'    : "2013tigge_2014-10-01_00061218.grib"
})

ECMWF members (i.e. licence holders, authorised users, staff and members of NHMSs in Member and Co-operating States):

You can use the 'mars' script with the MARS syntax or you can request it from Python using this class:

#!/usr/bin/env python
from ecmwfapi import ECMWFService
  
server = ECMWFService("mars")
server.execute(
    {
    "class": "od09-01/to/2013-09-30",
    "type" "date": "20150101",
    "expver": "an1",
    "levtype": "classsfc",
    "param": "ei167.128",
    "step": "0/to/240/by/12",
    "stream": "oper",
    "target" "time": "00",
    "type": "data.gribfc"
    },
    "target.grib")
