Activities
Activities
are taking place in several interoperating subprojects (TP) and working
packages (AP). Subprojects are defined for considering the North Sea (TP
1), the Baltic Sea (TP 2), inland waters (TP
3), land surface (TP 4), atmosphere (TP
5), and the MERIS-VA software (TP 6).
The
essential aim of MAPP is the operational production of enhanced geophysical
data for the purpose of climate and environmental research as well as
environmental monitoring and management. In order to assure the usability
of MAPP data products, forthcoming users are involved in the development
of data products from the beginning. Selected users are provided with
preliminary products to test their applicability and, if necessary, the
next generation products are refined according to the user's reports.
For each subproject suitable partners have been selected to prepare specific
application concepts. These concepts will be tested in form of demonstration
projects.

General: Meeting of the Arbeitskreis Fernerkundung, user workshop
TP 1. North Sea
Activities in TP 1 are currently focused on the validation of the atmospheric
correction and the resulting water constituent products. Further efforts
are the production of times series using the MERIS-VA software and their
representation in form of thematic maps. Demonstration projects will
be realized in cooperation with the Landesamt für Natur und Umwelt of
Schleswig-Holstein.

3. Inland waters
In preparation.
TP
4. Land surface
Within the MERIS Applications and Regional Products Project (MAPP), two land
products are developed:
- an operational algorithm for generating a land cover / land use map of
Germany, based on multi-temporal MERIS full resolution data. The proposed
algorithm is composed of a multi-spectral maximum-likelihood classification
and a multi-temporal analysis. By building a multi-spectral database and multi-temporal
reference vectors, the classification can be updated automatically every year.
- an Advanced Very High Resolution Radiometer (AVHRR) compatible vegetation
index called "AVHRR compatible NDVI" which based on radiative transfer models
for simulating the reflectance of the broad spectral channels of the NOAA
- AVHRR and the narrow spectral bands of MERIS. Linear combinations of the
MERIS reflectances in the red and near-infrared describe the AVHRR reflectance
in channel 1 and 2. The model takes into account
- atmospheric effects by using the Simplified Method for Atmospheric
Correction (SMAC),
- canopy and soil reflectance and transmission using the Scattering of
Arbitrarily Inclined Leaf (SAIL) model and
- leaf reflectance and transmittance using the Stochastic model for Leaf
Optical Properties Extended for fluorescence (SLOPE).
For further information please visist the WDC NDVI site.
TP
5. Atmosphere
Similar to TP 1, activities in TP 5 are focused on the validation of
data products. In particular aerosol and cloud products are validated
with concurrent airborne measurements using a sun photometer developed
by the Institute for Space Sciences of the FU Berlin, the Portable Lidar
System (POLIS) and the Compact Airborne Spectrographic Imager (CASI).
Demonstration projects in cooperation with the Max Planck Institute
for Meteorology have been started.
TP
6. MERIS-VA software
In TP 6 most attention is currently given on the completion of the operational
Level 2 processing software with plugins for water constituents, cloud,
and water vapour products. Further activities are the adaption of the
Level 3 processor to updated Level 2 products and modifications of the
Data Management and Information System of the DLR, and the running of
user workshops and courses.
