A custom ftp directory is available for a series of floats managed by Coriolis DAC.
These floats have some features that cannot be correctly reported in the existing data format.
Here are the 5 new features managed in these files.
1. Profiles with different sampling schemes
During a cycle, vertical profiles with different sampling schemes can now be reported.
Example : Apex float 6900848 (version 061609) performs a Near Surface Temperature Monitoring (NST).
There are 3 separate profiles for each cycle; the variable VERTICAL_SAMPLING_SCHEME records the 3 values :
- "Argo CTD sampling" : P,T,S observations from 2000 dbar to 25 dbar
- "Non pump near surface PT" : P, T from 20 dbar to surface
- "Pump near surface PTS" : P, T, S from 20 dbar to 5 dbar
2. Metadata format version 2.3
In these files, more configuration parameters are distributed; they are managed with the 2 variables :
CONFIGURATION_PARAMETER_NAME, CONFIGURATION_PARAMETER_VALUE
Example :
3. Technical data format version 2.3
In these files, technical parameters are managed with the 2 variables :
TECHNICAL_PARAMETER_NAME, TECHNICAL_PARAMETER_VALUE
4. Trajectory files format version 2.3
The new variable CYCLE_STAGE is available, for a better description of the locations.
5. A series of 16 additionnal physical parameters
