The ICEBRIDGE data loosely comforms to the ICARTT data format. Please consult the ICARTT Data Fromat document (IcarttDataFormat.pdf or http://www-air.larc.nasa.gov/missions/etc/IcarttDataFormat.htm) for more details. Note: Some PIs used spaces or tab as delimiters instead of the comma that is specified in the data format document other than this difference in delimiters the data is in the correct format. File naming convention for ICARTT: Features of different file naming conventions (including Ames) have been adapted here. File names for the ICARTT data format, limited to 127 characters or less, are defined as follows: dataID_locationID_YYYYMMDD[hh[mm[ss]]]_R#[_L#][_V#][_comments].extension, where the only allowed characters are: a-zA-Z0-9_.- (that is, upper case and lower case alphanumeric, underscore, period, and hyphen). All fields not in square brackets are required and are described as follows: dataID: short description of measured parameter/species, instrument, or model (e.g., O3; RH; VOC; PTRMS; MM5) locationID: short description of site; station; platform; laboratory or institute YYYY: four-digit year MM: two-digit month DD: two-digit day hh: optional two-digit hour mm: optional two-digit minute ss: optional two-digit second R: revision number of data L: optional launch number V: optional volume number comments: optional additional information extension: file type descriptor (see ICARTT Data Format Document for more details).
