DateIndividual/OrganisationFeedback and suggestionsAction
18 February 2013 Philippe Caroff, Meteo-France Addition of disturbance development types. Added post-tropical depression and remnant low to development enumeration.  
25 January 2008 Tim Hewson, Met Office
 Add elements to represent extratropical cyclone diagnostics as done in the Met Office's cyclone database (click here to see list of diagnostics)  
29 January 2008 Nick Bower, RPS Metocean Engineers
 In creating a schema and namespace, CXML is not just a standard format for data exchange, but also a way to mix standard with local storage and analysis requirements in a way not possible with previous formats. Users can provide local additional enrichment to CXML based data without corrupting the standard, or even add CXML constructs to existing XML data. (none)
30 January 2008 John Knaff, CIRA
 Add elements to represent multiple fixes from different platforms, multiple radii of maximum wind and eye diameters, environmental pressure and tangential winds at fixed radii (say 500km, 1000km). Done (v.0.2)
2 February 2008 John Knaff, CIRA
 Include confidence/accuracy information on fix data Done (v.0.2)
4 February 2008 Bruce Harper, Systems Engineering Australia
 Include averaging times with wind measurements and estimates Done (v.0.2)
5 February 2008 Jeff Kepert, Bureau of Meteorology
 Allow for estimates of precision and/or rounding. Include greater detail on Dvorak parameters Precision added (v.0.2)
8 February 2008 Tim Marchok, GFDL
 Break the model resolution into 2 separate identifiers, one for model resolution and one for gridded output data resolution Done (v.0.2)
12 February 2008 Ian Shepherd, Bureau of Meteorology
 Tropical cyclone nomenclature is different for different regions and are based on different wind averaging periods. A system can be defined uniquely by its wind speed range and wind averaging period. Many nomenclatures available for use in CXML
15 February 2008 Samuel Westrelin, Meteo-France
 This XML format appears to be a good opportunity to get a consensus on the cyclone ID, which varies for different organizations no consensus yet
18 February 2008 Justin Ma, HKO
 Provide detailed description of all parameters to avoid mis-interpretation Draft CXML manual written
21 February 2008 Chris Sisko, NHC
 The proposal for CXML has merit and if the format specification is clearly and extensively documented, I believe that CXML would be widely adopted and could be provided in real-time for external use. Click here for full comments, and here for replies. (none)
22 February 2008 Andrew Burton, Bureau of Meteorology
 Expanded Dvorak parameters Done (v.0.2)
3 March 2008 Philippe Caroff, MeteoFrance
 Include all items in WMO Best Track format (2002) source attribute added to record observations source for various cyclone data
11 May 2008 Mike Charles, NCEP
 Include information on tracking domain Optional trackingDomain element added to metadata
4 June 2008 Mike Charles, NCEP
 Include continent names in subregions to enable extra-tropical cyclone tracking Continents added to list of allowable subregions (v.1.0)
17 June 2008 Baudouin Raoult, ECMWF
 basin element differs from the WMO basin abbreviations in the file names. Units should be enforced for consistency. Basin names modified to be consistent with WMO documents (v.1.1), units specifically enumerated
24 August 2009 Philippe Caroff, Meteo-France
 Source of data for radius of maximum winds should be described. (v.1.2) radius element now includes an optional source attribute.
