Dear CDAAC Data User:
A bug has been found in the champ2014 reprocessing.
Data in atmPrf flies in this mission are affected by an error due to
inconsistent smoothing of L1 and L1-L2 bending angles used for the ionospheric
correction of the optimized bending angle. This error manifests itself
in random errors above 30 km for occultations with large ionospheric
The profiles affected by this error are:
- Optimized bending angle
Non-optimized bending angle profiles are not affected by this error.
Currently, this error is fixed in the CDAAC software. Only the champ2014 reprocessing is affected.
We plan on publishing a champ2016 reprocessing that fixes this error by the end of the year.
Sorry for the inconvenience,
Ben Ho, Sergey Sokolovskiy and the CDAAC team
