HOT cruises Meteorological Observations University of Hawaii October, 7, 1997 The Hawaiian Ocean Time series experiment (HOT) Meteorological observation data are stored in ASCII files. Two data formats exist. Cruises 1 through 27 are written in the first format that contains only numeric data (files met1_#.dat, where # is the cruise number). Starting with cruise 28, the data exist in the original format and in the second format (files met2_#.dat) that contains some character fields (e.g. Type of cloud) in addition to the numerical data . Data files from the ALOHA-Climax cruises have names with the prefix ac (e.g. acmet1_#.dat and acmet2_#.dat). The Readme.met1 and Readme.met2 explain the corresponding file formats.
