Mobile system for atmospheric temperature profile monitoring: mobile MTP-5
Introduction
Studies of ground temperature
heterogeneity show that the heat island inside
of the city can have heterogeneous structure
so-called "multicupolas". But this assumes, in
turn, the three-dimensional heterogeneity of
temperature profile. Thus, in the city can be
observed different conditions for forming and
destroying the inversions and, therefore, can
be formed different prerequisites for pollution
concentration increase in the Atmospheric
Boundary Layer (ABL).
MMTP-5
Mobile system for atmospheric temperature profile monitoring: mobile MTP-5
The technique and equipment used in the
measurements.
The investigations of space heterogeneity of
atmospheric temperature stratification were
carried out by mobile system MMTP-5 in the
large city Nijny Novgorod and in its suburb in
August-October 2004. The measurements of
temperature profiles were conducted
simultaneously by MMTP-5 and by stationary
MTP-5 installed on the roof of hotel “Oka” at
the altitude 235 m. The special equipment
installed on the mobile system MMTP-5
allowed measuring air pollution concentration.
The results of temperature profile
measurements in 12 points of Nijny Novgorod
and its suburb (5 points) are presented in this
report.

Features of MMTP-5 construction
1)
Absence of any microwave units inside the car – installation on
the roof of car.
2)
Harsh weather and road condition protection – installation inside
the standard car roof box.
3)
Vibrating protection against car structure vibration and vibration
caused by the road – three levels of vibrating protection:
a) Solid state assembling of microwave radiometer;
b) Vibrating isolation of microwave radiometer and housing
c) Vibrating isolation of the complete system and car body in
transport position
4)
Power supply on the base of standard car battery – set of power
converters and stabilizers
5)
On line time and space location – GPS and GSM modem
integrated in to the process of measurements

Conclusion
The measurements of temperature stratification in the Nijny-Novgorod
industrial agglomeration carried out by means of mobile (MMTP-5) and stationary
temperature profilers MTP-5 showed:
Mobile measuring temperature profiler MMTP-5 allows to investigate the spatial
variability of atmospheric boundary layer temperature stratification.
In the inspected territory it was observed 3-5 sufficiently well resolved and steady
zones distinguishing by the thermal structure of ABL. These zones are coupled with
the orographical features of the city. The sizes and internal structure of these zones
depended on the synoptic situation.
 The zone of representative using of stationary MTP-5 data for the forecast of bad
weather conditions (BWC) was determined on the basis of data obtained during
these measurements. As consequent from the analysis, the data of stationary MTP-5
can be used regularly in the forecast of BWC within the radius 6-8 km. The
extending of forecast to entire territory on the city and its suburb is possibly only
under the specified synoptic conditions.
