This page is automatically created by code which scans all files
in the Argo USGODAE GDAC.
All values are the number of floats exhibiting the described conditions
for each DAC.
| # floats | number of floats in total |
|---|
| Any DM | number of floats with any DM files |
|---|
| DM - missing P ADJ | floats with some DM files having empty or missing PRES_ADJUSTED (where there is a non-empty PRES profile) |
|---|
| RT - missing P ADJ | floats with some RT files having empty or missing PRES_ADJUSTED (where there is a non-empty PRES profile) |
|---|
| 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 (ie 5 dbar, or 0 dbar)
can be resolved (or guessed) from the surface pressure parameter name |
|---|
| P=Praw-SP | pressure does required correction by subtracting SP |
|---|
| P type unknown | don't know if is the above type of float |
|---|
| Pcor varies in prof |
Praw-Padj is not constant through profile. This now excludes SOLOs where
deepest ADJUSTED pressure is correct forincomplete bin averaging. |
|---|
| Some Praw-Padj | float does have some Praw and corresponding Padj values, so a "DAC correction" can be resolved. |
|---|
| Some valid SP | tech file has some plausible SP values (only required where pressure has to be corrected with SP) |
|---|
| 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) |
|---|
| 80% > 1dbar | 80% of DAC corrections disagree with our estimatesby at least 1dbar |
|---|
| 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 |
|---|
