Key changes:

 postProc_20260115 (version 0028.0004 released on 20260115)

1. Less filtering is applied, so expect to see more variation in bending angle and refractivity.

2. No interpolation is applied, so small gaps in the bending angle and refractivity are expected.

3. Negative values (refractivity, bending angle, height, pressure, and temperature) as well as NaNs are removed from the atmPrf profiles.

4. The top ~10 points (~0.5 km) are more likely to be contaminated by outliers and should be used with caution or excluded.

5. p, T, and q retrieved from ERA-5 now replace aircraft flight-level MET data for bending angle and refractivity calculations.

  C-130: noticeable improvement near the top of the profiles in bending angle (bias corrected).

  G-IV: small improvement in bending angle, large improvement in dry temperature and pressure.

In the archive folder, you will find two early versions:

 postProc_20250317 (version 0027.0004 released on 20250317): 

Using aircraft flight-level MET data, with filtering and quality control procedures that differ.
 
 postProc_20260108 (version 0027.0004 released on 20260108): 

Similar to 20260115, but with some technical issues in the data format.
