INSTITUTE OF METEOROLOGY AND WATER MANAGEMENT
IMGW in general
IMGW is a research and development unit established on the basis of
the decree No. 338/72 of 30.12.1972, issued by the Council of Ministers.
IMGW is the National Hydro-Meteorological Service which operates in
support of public sector as well as commercial firms and offers various
services and expertises in the field of meteorology and hydrology.

„COPAL - aircraft” potential usage by IMGW
Centre of Numerical Weather Forecasting, COSMO-PL model, Warsaw
1. Validation of micro physics parametrisation
schemes applied for COSMO-PL.
* comparison between values of precipitable
water obtained from model on chosen levels
within the cloudy area with adequate “in situ”
measurements (e.g. performed by Lyman Alfa
hygrometer or fast-FFSP probes)
2. Nudging of drop-sounding vertical profiles,
performed over south-eastern part of Poland
within COSMO model for specific synoptic
situations.
* case study COSMO simulations based on those
profiles could answer if there is a real need for
establishing additional regular radiosonde
station.
3. Field capaigns focused on dynamics of
synoptic- and meso-scale weather systems in
Central Europe, using drop-sounding vertical
profiles, cloud microphysical data, etc.

Overshooting Tops (OST) phenomena
investigation.
OST are a dome-like protrusion that extends
above the Cumulonimbus anvil, into the
stratosphere which is associated with strong
convection and severe weather - storm,
lightnings, heavy rain, hail, funnel clouds.
For OST monitoring specified output image is
defined. It is based on the difference of
brightness temperatures between two infra red
spectral channels of Geostationary satellite –
Meteosat 9 : WV (water vapour) 6,2 um and
10,8 um. Indication of OST is when the
difference > 0.
Although recognition of OST is quite easy,
physical interpretation of this so called Warm
Water Vapour Pixel is still under consideration.

Data collection ( at least temperature and humidity) both inside and above
the cloud, could help for understanding OST processes and point what are
necessary conditions for its establishing. The campaign would confirm if
the OST really break the tropopause, how deep they are, and the state of
the cloud environment in the lower stratosphere.
Horizontal leg above the convective cell, before the OST stage, could point
if there is any kind of additional triggering, e.g. higher values of water
vapour in the lower part of stratosphere which lead to well developed OST
stage (besides of very strong dynamics of the cloud and powerful updraft
connected with it, which is the standard interpretation of the OST onset).
Additional aim of the campaign would be the validation of satellite derived
indicators for OST.
The whole OST investigation would lead to better monitoring and better
warnings of severe weather conditions associated with it.

1. Validation of satellite derived specific humidity and temperature profiles.
* Obtained from MSG (Meteosat Second Generation), used for calculation of GII
(Global Instability Index), helpful for severe storm prediction.
** Obtained from NOAA satellites, used as initial conditions within data assimilation
scheme for COSMO-PL NWP model.
The aim of the campaign - comparison of „in situ” based and via satellite retrieval
algorithm derived profiles, localized along the scan line.
As the GII product was basically created for American synoptic area, calibration
based on collected data, could help to build modified instability indices better suited
for local European conditions.
2. Validation of satellite derived soil moisture and snow cover.
* Possible to obtain via microwave MSG or METOP (Meteorological Operation
satellite) sensors.
** Potentially useful for incorporation to COSMO-PL model initial conditions and for
hydrological models.
The aim of the campaign - comparison of land emissivity properties near ground
level and soil moisture or snow cover characteristics obtained from those
measurements with the values derived on satellite based data.

Centre for pollution transport modelling and monitoring, Katowice
1. Vertical distributions of H-3, Be-7, Na-22, C-14, Cs-137, Pb-210, Rn-222 (Pb218) measurements.
* isotopes mentioned above are considered as good tracers associated with
polluted air masses. Airborne measurements of their distributions could give
significant input for improvement of air pollution transport models.
2. Investigations of polluted plums from high level sources, with special focus on
NOx (for adjustment of gas dispersion parameterisation formulas)
* a potential usage of a correlative spectrophotometer COSPEC - its utility for SO2
plum spatial characteristics is well proven and its installation on the “COPAL –
aircraft” could be potentially beneficial for atmospheric pollution monitoring and
research.

Centre of Aerology, Legionowo
1. Vertical distribution of aerosols and their micro physical properties discrimination between natural and anthropogenic aerosols.
* airborne “in-situ” measurements as an additional source of data.
2. Distribution and variability of water vapour and ozone concentrations in
the troposphere – investigations of the ozone and water vapour relations in
the upper troposphere.
* vertical distribution of ozone, water vapour and direct OH concentrations
from aircraft measurements.
