EOMF-05. robspack, a fast R package to read, process and plot NOAA/GML ObsPack
Abstract
Observations of greenhouse gas emissions are critical to monitor the state of the
atmosphere, quantify present and historical emissions, and understand global climate
change. Observation Package (ObsPack) is a specific format to deliver atmospheric
measurements data of trace gasses (Masarie, Peters, Jacobson, & Tans, 2014).
However, processing ObsPack products (i.e. GLOBALVIEW) and selecting specific
observations for modeling purposes can be cumbersome, as they generally contain
hundreds of files. Hence, we developed an open-source R package “robspack” to read,
process and plot NOAA/GML ObsPack products. We used an CH4 ObsPack as an
example in our code. But it can be easily modified to process ObsPack products for
other greenhouse gasses.
