 === Progress so far:

-WP-I1.1, WP-I1.4, and WP-I1.8 have started 
+We prepared a contribution to the publication describing the implementation of the chemistry model in the PALM model system 6.0 (Khan, et al., 2021). A case study has also been included comparing four different chemical mechanisms.

+
+The development of a biogenic emission model is in progress (WP-I1.1). The code development is completed, however, the model code needs to be ported to the recently introduced data structure that provides a two stage interface for all current and future emission modules. The rationale behind the new code structure remains convenience, code elegance and computational efficiency. A publication is in preparation.
+
+The architecture for the development of a new module for the introduction of volume sources from different emission sectors or modes such as domestic heating, aviation and biogenic emissions is presented in Figure 5 (WP-I1.4). So far only emissions have been implemented as surface fluxes.

+   '''Figure 5:'''Architecture of the new module for the generalised volume sources, e.g. here for traffic emissions or biogenic emissions.
+
+The development of a graphics-based algorithm for chimney position location (see example in Figure 6) is based on the geometric centre of each connected building according to an approach following Struschka and Li (2019, internal report in the line of a subcontract in MOSAIK phase 1) (WP-I1.4).

+
+
+We cooperate and exchange data with WP-I2 (TUB) on dynamic traffic-related emissions for the pollutant dispersion calculation in PALM-4U (WP-I1.4)
+
+A Python based dynamic driver has been developed to provide realistic mesoscale forcings from WRF output data to PALM-4U. A journal paper, Lin et al.,(2020), has been accepted for publication in Geoscientific Model Development (WP-I1.7). 
+
+With the available nco-cdo based tool, output from WRF-Chem will be used to provide mesoscale chemistry forcing for PALM-4U chemistry simulations (WP-I1.7).
+
+A publication is in preparation including a comprehensive evaluation of the chemistry model in PALM-4U. For this purpose, nested model runs for different domains were set up (see one example in Figure 7), which are to be evaluated on the basis of available measurement data (WP-I1.7).

+
+
+Technical support and advice for the chemistry model in relation to PALM-4U evaluation runs is being provided as and when required (WP-I1.8).
+
+Chemistry model training and support is provided in PALM Seminar in February and September 2020, and also in February 2021.
