Contents of CLIMAT (TEMP) (SHIP) Messages

CLIMAT-messages contain comprehensive information on a variety of climate-relevant meteorological parameters such as monthly mean temperature, mean daily maximum and minimum temperatures of the month, monthly mean pressure, monthly mean vapour pressure, total precipitation for the month and total sunshine for the month. Information on so-called normal values of these parameters, usually averaged over a period of 30 years for a specific month, can also be transmitted with CLIMAT-messages. Data on extreme values of certain parameters and days of a month with certain parameters exceeding defined thresholds can also be included, as well as information on the number of days of a month where data are missing for a certain parameter. CLIMAT SHIP messages contain information on fewer variables (e.g., total sunshine for the month and extreme values are not included). CLIMAT TEMP (SHIP)-messages contain information on monthly mean temperature, monthly mean geopotential, monthly mean dew-point depression and wind characteristics at specific pressure surfaces.

Famous quotes containing the words contents and/or messages:

    To be, contents his natural desire;
    He asks no Angel’s wing, no Seraph’s fire;
    But thinks, admitted to that equal sky,
    His faithful dog shall bear him company.
    Alexander Pope (1688–1744)

    The first of the undecoded messages read: “Popeye sits in thunder,
    Unthought of. From that shoebox of an apartment,
    From livid curtain’s hue, a tangram emerges: a country.”
    John Ashbery (b. 1927)
