The research aims to study the effect of weather (humidity - pressure - temperature) on
the linear measurements between geodesic network points through the introduction of
these factors directly on the Total station devices settings and get distanc
es patched for that
network has been based geodesic point (conducting field measurements necessary) within
easy reach of the design requirements of the device ideal conditions in the study area
(Trjano) in the province of Latakia, which we will adopt in the later stages to monitor
landslides and thus all measurement cycles will be compare basic measurement cycle
taking into account changes in ambient weather conditions in each measurement cycle for
the reference measurement cycle.
This research includes a detailed study of the daily and monthly
changes to the intensity of total solar radiation in the city of Homs
(34.75N °, 36.7 E °), and a direct measurement of the intensity. The
study shows that intensity increases to max
imum values in summer
1100w / m2, and drops to lesser values in winter 600 w / m2. The
difference between the measured values in summer and winter is
due to: a change in the inclination of the sun, and implicitly solar
azimuth z. This angle is at its greatest in winter and the optical
path is at the maximum. Thus, the processes of scattering and
absorption increase. In summer, the inclination angle is at its lowest
and the optical path is at the minimum. Thus, the absorption and
scattering of solar radiation are at the minimum.
