UAR Report

This element defines one particular combined Rawinsonde and Pibal observation report. Its main contents is a sequence of UALEVELs that describe a set of weather conditions at particular vertical atmospheric pressure levels.

Raw rawinsonde observation reports are highly unsuitable for any further processing or even human analysis. Not only the information is spread through several parts, which are delivered in separate messages; the information is also encoded; without an extensive set of code tables (Appendix E-III of FMH-3 below) the data are inaccessible. The OMF markup aims to aid processing and understanding of a report by annotating the raw data with decoded quantities (pressure, temperature, dew point depression, wind vector) in conventional and self-evident units. Furthermore, a reference to an observation station is annotated with the station's full name, location and elevation; time stamps are always presented in EPOCH seconds.

The Federal Meteorological Handbook No. 3 -- FMH-3 below -- "prescribes federal standards for taking rawinsonde and pibal observations; for processing the observations; and for encoding, telecommunicating, and archiving the data. Also provided are procedures for quality control throughout the various phases of data acquisition, processing, and dissemination. All methodology contained in the Handbook is consistent with that stipulated by the World Meteorological Organization (WMO). "

The OMF markup described in this document only annotates the raw text of Rawinsonde and Pibal Observation reports, without altering them or omitting a single letter. An annotated UAR report combines all four parts of the original report (as well as accompanying Pibal reports if applicable) and presents the levels in a logical sequence. Yet, the markup contains explicit "pointers" that refer back to originating parts. Thus it is always possible to reconstruct the original messages of a raw report. In case of a coding or transmission error, the corresponding data are marked with a specific tag. It is up to an application then to try to correct the error and salvage whatever data possible.

UAPART Element

The UAPART element identifies a part of a combined Rawinsonde/Pibal observation. The results of an upper-air observation are reported in up to four separate messages; a rawinsonde report may also be accompanied by related pilot balloon reports (which may include four parts as well).

The body of the element is an identification token YYGGId, which is the second token of Section 1 of a report's part [E-II.2.1 and E-I.2.1 of FMH-3].



 the id of a part. an NMTOKEN
A four-character string of a form "MiMiMjMj" where MiMi identify a report: TT, UU, XX, II, PP, QQ, or EE. The other two characters identify one of the four parts of a report: AA, BB, CC, or DD
  This id is the the first word of the identifying section -- Section 1 -- of a rawinsonde or a pibal report. See E-II.2.1 and E-I.2.1 of FMH-3.

Note, part ids are unique within a single UAR element.

 a reference to a part. an NMTOKEN
precisely as the one above
  All other minor elements within a UAR element contain this attribute to refer to a part where that element's content came from. It is this reference that permits the perfect reconstruction of any part of the original rawinsonde or a pibal message from a combined and annotated UAR report.


UAID Element

The UAID element tells more details about conditions and circumstances a particular rawinsonde observation was carried out. Specifically, this element provides data on a particular sounding and tracking system used, precise time of an observation, and, optionally, the sea-surface temperature. The body of the UAID element is two or three words that constitute Section 7 of a report (the words that follow the section identifier 31313) [E-II.2.7 of FMH-3].


UACODE Element

The UACODE element marks up those tokens of the original message that are unparsed or cannot be parsed. Currently Sections 8, 9 and 10 of a rawinsonde report, and Sections 4, 5 and 6 of a pibal report are not parsed. These sections either contain regional codes, or specify levels that do not have any attributed pressure value. See Appendices E-I and E-II of FMH-3 for more details.

Occasionally some of report's data cannot be parsed because they were wrongly encoded or garbled during transmission.

Regardless of the reason, the unparsed parts of a report are thus clearly identified so an application may attempt to extract or salvage whatever information possible. The present markup format does not correct or modify these unparsed pieces, and does not annotate them any further. The unparsed tokens identified by an UACODE element always occur at the very end of a part referred to by a Ref attribute. This implies that there may be at most one UACODE element referring to a particular part. As a UAR element however may include several UAPARTs, there may be several UACODE elements within a single UAR report.



This element contains a sequence of UALEVEL elements for each particular vertical atmospheric level described in a whole UAR report. The sequence of UALEVELs is ordered in descending order with respect to levels' pressure. Certain pressure levels -- for example, surface, tropopause or maximum wind -- can be described in several parts of the original observation report. Therefore, there may be several UALEVELs corresponding to exactly the same pressure value. The other attributes of these levels may be identical as well, or may differ. It is up to an application to choose the most appropriate values.




The UALEVEL element is the most interesting one as it conveys detailed information about one particular isobaric surface - both in a raw and decoded formats. The body of the element is encoded information about a pressure level exactly as it appeared in one particular part of a report. A required P attribute tells the pressure value of a UALEVEL element; a required Ref element points to a part of the original rawinsonde or pibal message that carried these encoded data. Together, P and Ref attributes identify a UALEVEL. As mentioned above, one P attribute may not be enough as some pressure levels may be described in several parts of a report - in identical or different terms. To uniquely identify a UALEVEL one also has to heed a H attribute: For example, if the maximum wind level happens to coincide with one of the standard pressure levels in Part TTAA, there will be two UALEVEL elements with identical values of P and Ref attributes.

The other attributes of a UALEVEL element present the element's encoded data in a fully-decoded, self-contained format.



 A reference to a UAPART that contained this element's (encoded) data
 a pressure value of an atmospheric layer
  • a positive, not necessarily integral, number, in hPa units
    One hectoPascal is numerically equal to one millibar
  • "UNKNOWN" in a PILOT report, where the pressure level has not been determined (yet)
 The standard pressure at zero altitude is 1013.250 hPa
 the geopotential height of the pressure level
  • a (possibly negative) number, in whole geopotential meters (MSL)
  • "SURF" for the surface level
  • "TROP" for a tropopause level
  • "MAXW" for a maximum wind level (other than the highest observed level)
  • "MAXWTOP" for a maximum wind level which is the top of the wind sounding
  • omitted
  The "MAXWTOP" symbol stands for code 66 of E-II.2.4, FMH-3, "when top of the wind sounding corresponds to the highest wind speed observed throughout the ascent. The top of the wind sounding is to be understood as the highest level for which wind data are available." See also Table 5300 (WMO-No. 306, Vol. I.1), FMH-3, Appendix E-III.
 the air temperature at this isobaric level a positive, zero or negative number, in degrees Celsius; may be omitted
 Depression of the dewpoint temperature (with respect to water) at this isobaric surface a non-negative number, in degrees Celsius; may be omitted
 wind vector at a specified level a string of a form "nnn, mm" or "nnn, mm bbb" or "nnn, mm ,aaa" or "nnn, mm bbb, aaa" or omitted
  Here nnn is a true direction from which wind is blowing, in degrees. This is an integer number within [0,360), with 0 meaning the wind is blowing from the true North, 270 stands for the wind blowing from the West. Normally this number has a precision of 5 degrees.
mm is the wind speed in meters per second.

If specified, bbb stands for the absolute value of the vector difference between the wind at a given level, and the wind 1 km below that level, in meters per second. The number aaa if given is the absolute value of the vector difference between the wind at a given level, and the wind 1 km above that level, in meters per second.
