Repeated testing of under dome astroclimate of AZT-33 telescope

SPIE Proceedings, 2009
Based on the results of repeated measurements of under dome airstreams parameters of the AZT-33 telescope, some conclusions have been drawn, allowing improvement in quality of astronomic images in the telescope. After fulfillment of a part of recommended works, changes of under dome climate were compared with the measurements of 2005.

CHANGES IN THE ASTROCLIMATE OF TADJIKISTAN'S HIGH MOUNTAIN OBSERVATORIES

Астрономический журнал / Astronomy Reports
The paper examines some parameters of the astroclimate of two high mountain observatories in Tajikistan: Sanglok and Shorbulak. Long-term variations and seasonal features of total cloud cover and deposited water vapor are analyzed according to the ERA5 ...

Result of measurements of the astroclimate characteristics of astronomical telescopes in the mountain observatories

SPIE Proceedings, 2009
The paper describes the results of the measurements of telescope actroclimate characteristics in the mountains on the lake Baikal shore and in the Sayan foothills. For the measurements a mobile ultrasonic meteorological system was used. It is shown that the place of arrangement of telescopes on the lake Baikal shore is favorable to daytime observations,

Ecuador's Astroclimate, 2010–2025

Country-scale astro-climatology and site-screening for Ecuador, integrating reanalysis, satellite, and geospatial layers into operational products for observatories. From ERA5 (2010–2025) we derive three night-time metrics—photometric clear-sky fraction (CSNF), precipitable water vapour (PWV), and 200-hPa wind speed (V200)—and combine them into an ...

Astroclimate parameters of the Kyiv observatories

2017
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-sky brightness is calculated using the images of standard stars in different filters.

Astroclimatic benchmarks of stratigraphic correlation for Neogene-Quaternary deposits

Moscow University Bulletin Series 4 Geology
An astrochronological (cyclostratigraphic) binding of the lithological and geochemical characteristics of the Neogene-Quaternary sediments of the sections to the Milankovich cycles (eccentricity, inclination of the ecliptic, precession) was carried out, an analysis of the relationship between the established variations of climate and paleotemperature ...
