Additional considerations
This section describes several operations that may simplify your use of the RV50X.
Selecting a data plan
Prior to selecting a data plan, it is wise to consider your data transfer needs and
what you wish to accomplish while accessing the instruments remotely. For
example, do you want daily or weekly status reports on the overall performance of
the system? Do you want to download raw eddy covariance data sets directly to your
computer?
The typical raw data volume when logging compressed .ghg eddy covariance files is
about 1 MB per half hour, or about 1.5 GB of raw data in 30 days. See
Table A-1
below for more details.

Actual data volume will vary depending on the instrument configuration, the number of configuration
files sent to the instruments, and other factors. The values given here are assume 10 samples per second
logging of the default variable set in an LI-7500RS.
