ObsPack summary
The first step consists in constructing a summary for the ObsPack.
This is required to read the data, but also, identify agl,
which is present in some of the file names. This function returns a
data.frame. Optionally, the user can indicate a path to
store the data.frame. obs_summary also prints
a summary of the data. The second argument is the categories, and by
default includes the categories shown below, to account for all the
files. Then the summary data.frame contains the columns
id as the full path to each file, name which
is the name or relative path of the file, n just an id,
sector such as tower, and the column agl which
indicates the agl indicated in the name of the file if
available. To read the documentation of this function, the user must run
?obs_summary.
We first define the categories
cate = c("aircraft-pfp",
"aircraft-insitu",
"aircraft-flask",
"surface-insitu",
"surface-flask",
"surface-pfp",
"tower-insitu",
"aircore",
"shipboard-insitu",
"shipboard-flask")
obs <- "Z:/obspack/obspack_ch4_1_GLOBALVIEWplus_v5.1_2023-03-08/data/nc/"
index <- obs_summary(obs = obs,
categories = cate)Number of files of index: 429
