4. SURFACE DATA QUALITY CONTROL
------------------------------------------------------------------------------
   NCEI flags each observation with a quality code that AERMET does not act
   on, so the GHCNh file is screened before processing.  Rejected values are
   blanked (treated as missing); no record is dropped and no value is altered.

   Observations screened            61981
   Rejected, NCEI suspect/erroneous 79
   Rejected, METAR cross-check      0

6. DATA COMPLETENESS
------------------------------------------------------------------------------
   EPA requires at least 90% valid data per calendar quarter.  The quarterly
   columns are the compliance test; the annual column is informational.

      Year       Q1       Q2       Q3       Q4     Annual   Result
      ----   ------   ------   ------   ------   --------   ------

7. PHYSICAL PLAUSIBILITY OF THE DELIVERED FILES
------------------------------------------------------------------------------
   Screening of the .sfc files as delivered.  Wind speeds above 25 m/s and
   temperatures outside -25 to +45 C are reported for review; a non-zero count
   does not by itself mean the data are wrong, but each should be explainable.

      Year   Max wind   Min temp   Max temp   ws>25 m/s   T out of range
      ----   --------   --------   --------   ---------   --------------
      2021     12.7 m/s    -7.2 C    35.7 C           0                0

------------------------------------------------------------------------------
8. CALMS AND MISSING DATA
------------------------------------------------------------------------------
   AERMOD excludes calm hours (wind speed below the 0.5 m/s threshold) and
   missing hours from the averaging period, and reports both in its own output.
   They are counted here so the modeller can anticipate them.

      Year   Calm hrs   Missing hrs   Valid hrs
      ----   --------   -----------   ---------
      2021        175            74        8686
      2022         75            28        8732
      2023        304            90        8670
      2024        241            86        8698

9. OUTPUT FILES
------------------------------------------------------------------------------
   Files without the US suffix were processed WITHOUT the ADJ_U* option; files
   with the US suffix were processed with METHOD STABLEBL ADJ_U*.  Use one set
   or the other consistently -- do not mix them within a single AERMOD run.
