Results of long-term meteorological observations
and measurements, carried out at the Zagreb-Grič Observatory for the period of
129 years, have been presented. Climatic data represent a homogeneous sequence,
as the location of the Observatory has remained unchanged, whereas instruments
inside the Observatory have been only slightly and insignificantly changed. In a
view of the fact that there are also autographs working at the Observatory and
that hourly values of meteorological parameters are available, the analyzed data
refer to the standard climatological observation times (7, 14 and 21 h).
The Zagreb-Grič Observatory was in charge of the Andrija Mohorovičić Geophysical Institute from the start of its work until 1986, and has since been put under the management of the State Hydrometeorological Institute. With their permission sequence of measurements was completed until 1990.
