摘要: In this paper, we report first-time observations of total column ozone (TCO), aerosol optical thickness (AOT) and precipitable water content (PWC) at five different wavelengths using compact, handheld, multichannel sun photometer (Microtops II ozonometer) Atigre village (16.74°N latitude, 74.37°E longitude, 604 ms altitude above sea level). The three filters 305 nm, 312 nm 320 nm are used to detect the TCO, while two 936 nm 1020 nm PWC AOT, respectively. We have been collecting data from September 1, 2017, 122 days selected December 31, present as first AOD PWC. mean values AOT found be 261.2 (± 9.22) DU, 0.25 (± 0.04) 1.98 (± 0.79) cm, respectively, during period. TCO measurements taken by Microtops ozonometer compared with monitoring instrument satellite over Atigre. that negatively correlated (− 0.54) monsoon season, they show positive correlation (0.63) other seasons 90% significance level. diurnal variation differ in post-monsoon season.
