An error was reported by a user unable to use the 'Save As' option to create a CSV file. However, the ASC, and NETCDF options of Save As work (arcGrid option was terminated after 120 seconds): **ERROR: variable unknown or not in data set: (data set ok ?): carbon_dioxide_in_free_troposphere set var/name=carbon_dioxide_in_free_troposphere1e6 carbon_dioxide_in_free_troposphere The problem seems to be that the dataset has an init file that renames the variable as follows: SET DATA ($data_url) set var/name=carbon_dioxide_in_free_troposphere1e6 carbon_dioxide_in_free_troposphere !<custom let/title="Monthly Carbon Dioxide in Troposphere (AIRS)"/units="ppmv" carbon_dioxide_in_free_troposphere = carbon_dioxide_in_free_troposphere1e6*1000000.0 DEFINE SYMBOL data_var = carbon_dioxide_in_free_troposphere !custom> The init file works for plots, line charts, and other options but not CSV. (website mynasadata.larc.nasa.gov, dataset: Atmosphere, Air Quality, Monthly Carbon Dioxide in Troposphere) I have not downloaded LAS 8.0 yet but wondered if this was corrected in LAS 8? Penny |
