Mode-S EHS derived meteorological information is available for NMHS, after signing a Non Disclosure Agreement.
Example of the present coverage
Coverage of MUAC Mode-S EHS derived meteorological data. Color scale indicates the lowest level at which an observation was detected.
The data is processed with all necessary corrections:
- Magnetic to true heading correction
- Heading corrections
- Airspeed corrections
The data will be delivered in three formats:
The data will be delivered every 15 minutes with a delay of 10 minutes.
At present the Mode-S EHS derived meteorological information will be distributed using personal ftp-account.
Please contact firstname.lastname@example.org for inquiries on data access.
The BUFR format used at present uses the AMDAR reduction in space and time. At present the new WMO AMDAR format is being implemented.
The new AMDAR version 7 format is implemented. Mode-S EHS meteorological observations can be distiguished from ACARS, etc. by the data subcategory.
- Mode-S EHS met observations: WMO BUFR data category 4, data subcategory 146
- Here you can find the BUFR table discriptions used to encode
Please adjust these tables to your need.
Mode-S EHS ascii
The ascii-format is :
Each line one observation
