Software
EMOSLIB
EMOSLIB 433 443 is needed to interpolate successfully the wave energy flux mean direction (wefxd) parameter introduced at IFS Cycle 43r1.
...
Older versions of GRIB API can decode the IFS Cycle 43r1 products successfully but users are advised to use at least GRIB API version 1.14.5, which provides full support for the octahedral reduced Gaussian grid.

Test data in MARS
Test data from the IFS Cycle 43r1 e-suite test suites are available in MARS. The data are available with experiment version 0070 (MARS keyword EXPVER=0070) starting from 06 UTC on 10 August 2016. Currently these data are from the beta testing stage.
The data can be accessed in MARS from:
- HRES (class=od, stream=oper, expver=70)
- Wave HRES (class=od, stream=wave, expver=70)
- ENS (class=od, stream=enfo, expver=70)
- 00 UTC cycle only
- ENS Wave (class=od, stream=waef, expver=70)
- 00 UTC cycle only
Only registered users of ECMWF computing systems will be able to access the test data sets in MARS.
...
Availability of test data from the release candidate testing stage in dissemination is expected to be announced during the week beginning 17 October 2016.
