This folder contains two sub-folders: 
 
(a) Data_files: Contains nocturnal mean values of the parameters used in this study during (Jan 2023-Dec 2024): A total of 5 text files are in this folder 

(b) Data_files_filled: Nightglow brightness and corresponding temperature data contain gaps due to moon, clouds and local scattering.  Artefact data are reconstructed in a continuous series using 
a harmonic fitting method. This method fits a combination of sinusoidal functions to the available valid data and then uses the fitted model to estimate the values at the missing time steps. 
In total, 118 data points were reconstructed for both brightness and temperature, 419 data points for O3 VMR, and 18 data points for OLR. All of these reconstructed datasets have been compiled 
and provided in the folder “Data_Files_Filled.”: A total of 4 text files are in this folder

The description of the text files in both the folders are provided below: 
 
(a) Data_files:
1. OH brightness.TXT: 
Two years (January 2023 to December 2024) of continuous measurement of the daily averaged brightness of P1(2), P1(3) and P1(4) rotational lines of OH(3-1) nightglow 
emission obtained from PRL Airglow InfraRed Spectrograph (PAIRS), from Ahmedabad. 

2. OH Rotational Temperature.TXT: 
This text file gives DOY vs PAIRS derived Rotational temperature. (Rotational Temperature is derived from the brightness ratio of P1(2) and P1(4) rotational lines of OH(3–1) Meinel band (Singh et al., 2023)).

3. MLT_Ozone.txt:
This text file provides DOY vs nightly mean O3 values centered over ahmedabad. (SABER Level 2A nighttime O3 VMR data are averaged within a ±5° latitude–longitude and 87±4 km altitude region centred over Ahmedabad for the period January 2023 to December 2024.)

4. OLR.txt:
This file provides daily mean OLR values as a function of DOY, centred over Ahmedabad for the two years 2023 and 2024.

5. Solar_flux_F10.7:
DOY vs solar flux at 10.7 cm radio emissions for the two years 2023 and 2024 is provided in this text file.


(b) Data_files_filled: 
This folder contains 4 text files after filling the data gap as described above. Solar flux data is continuous; the other 4 files are given the same name as in the Data_files folder. 
All files contain 731 data potints corresponding to DOY 1- DOY 731 (DOY1: 1/1/2023, DOY 731: 31/12/2024)
