deck701: Missing Hour in observations and more missing CDM codes

cc. @dyb, @eck

We have successfully mapped the following fields extracted from the c99 attachment:

  • Original Lat and Lon converted to degrees with a precision of 2 decimals.

  • Original values and units for: AT, SLP and SST

  • For the air temperature and SLP hour of observation has also been mapped in the date_time of the record.

  • Ship name: I have created a code table that matches the corresponding ICOADS.core.ID to the long string Name from the online documentation found here

I still have a question regarding the duplicated IDs:

cnship not unique in pos. 1-8:   original:                 frequency:

Can I leave only one KEY and NAME e.g. only one SAM*_ROB?

We have mapped the following fields but the codes tables are still incomplete due to:

  • Platform sub-type: I have identified the different type of sailing ships, grouped them into categories and assigned a code from the CDM for those type of ships that are in the CDM. However, more codes in the CDM are needed and a deep review of the categories that assigned to each sailing ship. A spread sheet with the categories and platform subtypes is located under the ICOADS_Documentation/structure folder

There is no barometer height information for this deck.

A first draft of the CDM-mapper for this deck can be found in the branch deck701. I will push this to github once we have a better idea of the CDM codes for the platform subtypes and a feedback on what to do with the missing hour.

According to Liz (@eck) for all these decks where the hour is missing noon is assigned.
