In this video, I'll show
In this video, I'll show you how you can access data from multiple NetCDF files in one R script. I will cover:
00:00 Introduction
02:06 Looping through multiple files
Pulling data based on variable names or pulling global attributes
16:30 Error handling
Skipping files where relevant information is not found, so you script doesn't crash!
23:45 Pull data based on the the CF standard_name attribute
This attribute is taken from the CF conventions. If different people create NetCDF-CF files including the same variable name, they should both assign the same standard_name variable attribute so a person (or script) can identify them as the same variable.
Data used in this video:
https://doi.org/10.21335/NMDC-1371694848
The data are in NetCDF-CF files, and are FAIR. The data are published to NMDC in a hierarchical way.
One page (and DOI) for whole project
One page (and DOI) for each cruise
One page (and DOI) for each cast - sometimes multiple casts at a single station. The file is here.
The scripts used are here:
Based on variable name: https://github.com/lhmarsden/NetCDF-C...
Based on standard_name: https://github.com/lhmarsden/NetCDF-C...
