This icon extracts values from complex BUFR messages where coordinate descriptors are required to locate particular data. generates plots of spectra as a function of Legendre polynomial order. The macro language equivalents are spec_graph() and spec_contour Briefly, when a BUFR element descriptor described as F'XX'YYY has an F of 0 and an XX of less than 10, it is a 'coordinate descriptor', which means that it retains its current value until redefined. In this way, a set of observations 'inherit' the same value for such a descriptor without it appearing explicitly for each observation. The purpose of this icon is to extract data that can only be described by using coordinate descriptors; for more complete BUFR data extraction, it can be used with BUFR output from the Observation Filter icon. The output is a geopoints file.The macro language equivalent is bufr_picker(). |

Data
Drop any icon containing or returning BUFR data. This may be, for example, a MARS Retrieval (of observations) icon, a BUFR file icon or an Observation Filter icon (provided it outputs BUFR, not geopoints).
