Clear sky fraction above Indonesia: an analysis for astronomical site selection

, 2012
We report a study of cloud cover over Indonesia based on meteorological satellite data, spanning over the past 15 years (from 1996 to 2010) in order to be able to select a new astronomical site capable to host a multi-wavelength astronomical observatory.

Particle detector calibration and performance for Horizon-T cosmic rays experiment [PDF]

, 2017
Due to large variation of particle density in EAS, a response linearity of each detector needs to be assessed. The number of photon in a photo multiplier tube (PMT) pulse allows inferring the deviation from linearity in each case.

Astroclimes – measuring the abundance of CO2 and CH4 in the Earth’s atmosphere using astronomical observations

RAS Techniques and Instruments
ABSTRACT Monitoring the abundance of greenhouse gases is necessary to quantify their impact on global warming and climate change. Carbon dioxide ($\mathrm{CO_{2}}$) and methane ($\mathrm{CH_{4}}$) are the two most important greenhouse gases when it comes to global warming. Although a number of satellites and ground-based networks measure

Astroclimate parameters of the Kyiv observatories [PDF]

, 2012
Astroclimate parameters such as the atmospheric extinction, the night-sky brightness, and the seeing are studied using the observational data obtained at some Kyiv observatories. The first parameter is determined using the brief Bouguer method. The night-
