Webinars: Introduction to NCL File Input/Output

September 3, 2014

These webinars are similar to the "File I/O" lecture we give in our NCL workshops, and are geared towards new users of NCL. There are two lecture webinars, and an interactive demo webinar.

These webinars assume you have basic knowledge of NCL syntax, and that you know what an NCL "NetCDF variable model" is (attributes, named dimensions, coordinate variables).

If you are new to NCL, we recommend that you watch this set of webinars first:

• Introduction to NCL
• NCL-NetCDF Relationship

Description

Webinar #1: Introduction to NCL File Input/Output: "supported" formats
September 3, 2014 at 1:00 PM MDT
Dennis Shea, presenter
Slides as a PDF file
Recorded presentation as MP4 file (76 MB)

This 49-minute webinar describes the "supported" file formats that NCL recognizes (NetCDF, GRIB, HDF, etc), how to read and examine these types of files (both on the UNIX command line and in an NCL script), how to read multiple files with one call, and how to write a NetCDF file.

Webinar #2: Introduction to NCL File Input/Output: ASCII and Fortran/C binary
September 3, 2014 at 2:00 PM MDT
Dennis Shea, presenter
Slides as a PDF file
Recorded presentation as MP4 file (63 MB)

This 31-minute webinar describes how to read ASCII text files, CSV (comma separated values) files, and binary files (Fortran and C). A short demo is given on reading an ASCII file using an NCL script.

Webinar #3: Introduction to NCL File Input/Output: interactive demo
September 3, 2014 @ 3:00 PM MDT
Dennis Shea, presenter, Mary Haley, typist
Recorded presentation as MP4 file (93 MB)

This is a 42-minute interactive demo showing how to use "ncl_filedump" to examine the contents of "supported" file formats like NetCDF, HDF, and GRIB. A short example of reading a variable off a NetCDF file using an NCL script is given.
