Is the CSAT3 warning not a diagnostic code?
FALSE
(disable_flag_on(1) = FALSE)
Enable covariance processing
(disable_flag_on(1) = TRUE)
Disable covariance processing
TRUE
Are any CSAT3 warning flags set?
Convert CSAT3 diagnostic word into seperate warning flags
Convert LI-7500 data from molar density to molar fraction
Convert LI-7500 data from molar density to mass density
Convert CSAT3 data for WindVector (): wind_east = -Uy, wind_north = Ux
- Load the FW05 data from (OFFSET - 0) scans back
- Load the KH20 data from (OFFSET - 0) scans back
- Load the LI-7500 data from (OFFSET - 1) scans back
- Load the CSAT3 data from (OFFSET - 2) scans back
Retrieve buffered data and apply the appropriate lag:
TRUE
>= offset?)
Are enough data buffered to undo sensor lags? (scan_count
