All values are the number of floats exhibiting the described conditions
for each DAC.
# floats | number of floats in total |
New format tech | tech file has new format |
The following pressure correction aspects are
deduced for each float based on the Surface Pressure Offset parameter name.
These deductions are recorded in this table.
|
SP offset deduced | the Apex SP adjustment is known (or guessed) |
P=Praw-SP | pressure does required correction by subtracting SP |
P type unknown | don't know if is the above type of float |
P(N)-SP(N+1) | Nth profile should be corrected with N+1st SP |
N+1 unknown | don't know if is the above type of float |
Pcor varies in prof | Praw-Padj is not constant through profile |
Some Praw-Padj | float does have some Praw and corresponding Padj values |
Some valid SP | tech file has some plausible SP values |
Some DAC vs Audit test | some pressure correction comparisons can
be made for these floats |
All agree | all DAC corrections agree exactly with our estimates |
All diffs < 1dbar | some discrepancy, but these are all < 1dbar |
Some diffs > 1dbar | some discrepancies are large (> 1 dbar) |
All disagree | all DAC corrections disagree with our estimates |
The minimum (ie near-surface) profile pressure value will
normally be about 5 dbar for the Apex floats. We examine the median of these values
for each float series, as another coarse guide to correct calibration. |
Med MPP < 2.5dbar | (such cases often have MPP near zero - maybe
self-calibrating pressure?) |
Med MPP < 7.5dbar | 2.5< MPP<7.5 - mostly close to 5 dbar |
Med MPP < 12.5 | 7.5< MPP<12.5 - many of these are ~ 10dbar ?? |
Med MPP > 12.5 | presumably some bad pressures |
