Proof of concept NLR QA and QAFIT software change specification

Refine the quality assessment capabilities of SERI QC and QCFIT and assign the names NLR QA and QAFIT to represent the update for assessing data quality of modern measurement technologies.

Contribution:

• QCFIT (this repository)
• SERI QC (SUNI repository)

Note that SERI QC and QCFIT softwares work independently. QCFIT script calls only basic utils functions (splitDate, utcCoversion, calculateZenith, and calculateAirmass) from SERI QC script.

Ignored SERI QC (Rahul's code) from this repository as this is outdated. Instead, made the SERI QC code improvement on SUNI. Workflow: Develop QCFIT software, generate .QC0/.QA0 file here, then use that generated file to SUNI/CLI/SERIQC (Paul's code) to continue the development.

Wishlist items:

1. Kt maximum

• Expanded curve positions -> Modifications to QCFIT

2. New boundary curve definition

• Boundary curve definitions
• Modifications to QCFIT
• Modifications to SERIQC

3. Kn maximums - no action required

4. Kt and Kn maximum by airmass

• Modifications to QCFIT
• Modifications to SERIQC

5. Daytime maximums and minimums

• Modifications to SERI QC

6. Nighttime maximums and minimums

7. Eliminating multiple integration times

• Modifications to QCFIT
• Modifications to SERIQC

8. CSV format

• Modifications to QCFIT

9. QA-zero file format changes

• QCFIT code changes
• SERI QC code changes (File generator could be ignored. Just focus on QA0 file parser. https://github.com/NatLabRockies/SUNI/blob/main/CLI/SERIQC/seriqc/qcfit.py)

10. Rayleigh Test

• SERI QC code changes

11. Add buffer on the boundaries (SERIQC/functions.py) -- Hold off till C program benchmarking is completed.

• Three component tests change from 0.03 to 0.02
• Two component tests change from 0.03 to 0
  • NEED TO CONFIRM: What if either GHI or DNI is missing? Should we still set 0 here?=> YES.
• Kt maximum buffer change from 0.1 to 0
• SERI QC code changes

QCFIT Improvement
