  • bin2nc.ncl read the equal ISCCP binaries use 'dsread' to create 2.5 grid create netCDF ISCCP.yyyymm.nc files
  • (optional) most efficient is to: ncrcat ISCCP.*.nc ISCCP.19832000.nc (this failed once so I did the following) ncrcat ISCCP.198*.nc isccp.19831989.nc ncrcat ISCCP.199*.nc isccp.19901999.nc ncrcat ISCCP.200*.nc isccp.20002000.nc ncrcat isccp.19831989.nc isccp.19901999.nc isccp.20002000.nc \ isccp.nc 'rm' isccp.19831989.nc 'rm' isccp.19901999.nc 'rm' isccp.20002000.nc in T42 dir ncrcat ISCCP.[12]*.T42.nc isccp.T42.nc in T63 dir ncrcat ISCCP.[12]*.T63.nc isccp.T63.nc
  • gridInterpolate.ncl interpolat the 2.5 grids to T42/T63
  • gridCompare.ncl Read data from the 2.5, T42 and T63 grids select variables plot global view at specified time(s) plot a time series
  • gridTimeSeries.ncl create time series of specified variables (a) at specified grid point; (b) global averages
  • gridClm.ncl climatologies of specified variables.
    • use gridClm.ncl on isccp.nc, isccp.T42.nc, isccp.T63.nc or
    • use gridClm.ncl_addfiles on ISCCP.[12]*.nc, ISCCP.[12]*.T42.nc, ISCCP.[12]*.T63.nc
