cops_ngps_cnrs_ztdiwv_d: hourly ZTD and hourly IWV from the final processing of the GPS data from CNRS.

Champollion, Cedric

Dataset
Summary
The ZTD (mm) is the 0-level product of the GPS data processing. It should be used for assimilation purpose.
The IWV (kg/m**2) is the 1-level product of the GPS data. The conversion from ZTD to IWV is done following Bevis et al. 1982.

The surface pressure and temperature used in ZTD to IWV conversion have been interpolated from nearby mesonet station.

Higher level products such as slant delays, tomography will be available upon demand in Summer 2008. Please contact
 cedric.champollion@nullaero.jussieu.fr
 for details.
Quicklooks of all products will available on the web site: http://eost.u-strasbg.fr/COPS

Description
ZTD accuracy: lt 10 mm
IWV accuracy: about 1-2 mm or kg/mm**2
Description
Gaps in the data are mainly due to power supply gaps.
