The slant column densities (SCDs) a

The slant column densities (SCDs) as well as total column densities (TCDs) of NO2, O-3, H2O and O-4 are derived with different SZAs in clear and cloudy sky conditions. The large enhancements and reductions in TCDs of the above gases are observed in thick cumulonimbus (Cb) clouds and thin high cirrus (Ci) clouds, respectively, compared to clear sky conditions. The enhancements in TCDs of O-3 appear to be due to photon diffusion, multiple Mie-scattering and multiple reflections between layered clouds or isolated patches of optically thick clouds. The reductions in TCDs due to optically thin clouds are noticed during the above period. The variations in TCDs of O-3 measured under cloudy sky are discussed with total cloud cover (octas) of different types of clouds such as low clouds (C (L) ), medium clouds (C (M) ) and high clouds (C (H) ) during May-November 2000. The variations in TCDs of O-3 measured in cloudy sky conditions are found to be well matched with cloud sensitive parameter colour index (CI) and found to be in good correlation. The TCDcloudy are derived using airmass factors (AMFs) computed without considering cloud cover and CI in radiative transfer (RT) model, whereas TCDmodel are derived using AMFs computed with considering cloud cover, cloud height and CI in RT model. The TCDmodel is the column density of illuminated cloudy effect," wrote G.S. Meena and colleagues.

Kepadatan kolom miring (SCDs) serta jumlah kepadatan kolom (TCDs) NO2, O-3, H2O dan O-4 yang berasal dengan SZAs berbeda dalam kondisi langit cerah dan berawan. Perangkat tambahan besar dan pengurangan TCDs gas di atas diamati dalam cumulonimbus yang tebal (Cb) awan dan tipis cirrus tinggi (Ci) awan, masing-masing, dibandingkan dengan kondisi langit cerah. Perangkat tambahan di TCDs dari O-3 tampaknya karena difusi foton, beberapa Mie-hamburan dan beberapa refleksi antara awan berlapis atau patch terisolasi dari awan optik tebal. Penurunan TCDs karena awan optik tipis perhatikan selama periode tersebut. Variasi dalam TCDs dari O-3 diukur bawah langit berawan dibahas dengan total tutupan awan (octas) dari berbagai jenis awan seperti awan rendah (C (L)), awan menengah (C (M)) dan awan tinggi (C (H)) selama Mei-November 2000. variasi TCDs dari O-3 diukur dalam kondisi langit mendung yang ditemukan baik cocok dengan indeks warna awan parameter sensitif (CI) dan ditemukan di korelasi yang baik. The TCDcloudy berasal menggunakan faktor airmass (AMFS) dihitung tanpa mempertimbangkan awan dan CI di transfer radiasi (RT) model, sedangkan TCDmodel yang diturunkan menggunakan AMFS dihitung dengan mempertimbangkan awan, ketinggian awan dan CI dalam model RT. The TCDmodel adalah densitas kolom efek berawan diterangi, "tulis GS Meena dan kolega.
