real-time remote monitoring is desired, various telemetry options (for example,
cellular, radio, etc.) are available to transmit the processed flux data. Certain
conditions may also allow remote transmittal of time series data. Contact

1/ Biomet and energy balance sensors used for this fill time estimate include the following: HMP155A, NR-LITE2, CS300,
LI200, LI190, SI-111, TE525MM, TCAV (qty 2), CS655 (qty 2), and HFP01 (qty 4)
microSD Flash cards from various manufacturers may have
slightly different memory sizes on their 2 GB, 8 GB, and 16 GB
cards, respectively. Also, as a card ages some of its sectors may
become unusable, decreasing the available memory. Fill time
estimates given in TABLE 6-5 are approximations for new cards.
Campbell Scientific recommends and supports only the use of
microSD cards obtained from Campbell Scientific. These cards
are industrial grade and have passed Campbell Scientific hardware
testing. Use of consumer grade cards substantially increases the
risk of data loss.
6.5 Output Tables
Besides the
Const_Table
(see Section 6.2 , Set Constants
(p. 36)
) and the
standard Public , Status , CPI Status , and DataTableInfo tables that the
datalogger reports, the program has eight output tables. TABLE 6-6 gives the
names of these output tables, along with a short description, the frequency at
which a record is written to the table, and the amount of memory allocated
from the CPU and SD card for each table.
The variable naming conventions used by AmeriFlux and other
flux networks have been adopted. Additionally, an output table
called Flux_AmeriFluxFormat reports the variables in the order
and format prescribed by AmeriFlux.
(see http://ameriflux.lbl.gov/data/aboutdata/data-variables/ ).
The
Flux_CSFormat
and
Flux_Notes
tables may have some of the same
outputs as they did in prior versions of closed-path flux system programs,
although variable names have been updated to conform to AmeriFlux
convention. If the user would prefer to have the data fields contained in the
Flux_Notes
table appended to the end of the
Flux_CSFormat
table rather than
being placed in a separate output table, this is possible by changing the
