Objectives :

Like WP0, WP4 is a transversal WP. While WP0 focuses on coordination with the aim of facilitate interaction between each WP’s, WP4 focuses on technical aspects related to the scientific WPs (WP1, 2 and 3). Therefore, the aim is to gather the different scientific communities around the tools used (instruments, data, analytical methods, models) to provide to the WP0 relevant analysis to define optimal strategy for answering to the scientific questions from the WPs 1-3.

The WP4 positioning in MIST is depicted in Figure 1 where one can see that the WP4 will be in permanent interactions (blue double arrows) with WPs 1, 2 and 3. In fact, each WP will transfer the information to WP4 in the event of the development of a new technical/methodological tool and WP4 will centralize this information flux, analyze technical means before a transfer towards WPs through the methodology described below.

In addition, the WP4 will be the MIST interlocutor with the available national (AERIS, ForM@Ter) and international databases.

Methodology:

As inputs, the different scientific WPs will provide the key parameters/combination of parameters needed to resolve scientific questions identified as a function of spatial and temporal scale and precision needed. Figure 4 resumes the approach we plan to use to analyze our instrumental and analytical means :

Figure 4: Approach used by WP4 to analyze instrumental and analytical means.

  1. The first step is to inventor each tool available in the different scientific communities.

  2. The second step is to classify them according their characteristics by cross analysis method. This step will allow identifying lack and needs with respect to the different key parameters identified by each WPs (example is presented below).

  3. The last step is to analyze the classification obtained as a function of process investigated as well as spatial and temporal scale for highlighting gaps and niches.

This will provide a rigorous state of art which allow the WP0 to support strategies to develop good practices and new approaches for the future.

WP4 aims at providing for each tools a relevant analysis in order to promote :

  • for instruments: new instrument development, new instrumental synergies and good practices;

  • for data: sustain existing data from campaign and network, define data standard to provide dataset for AERIS and FORM@TER database, and as consequence promote access and dissemination;

  • for method : promote common data retrieval process, improve data processing to provide quasi real-time data retrieval;

  • for models specific attention will be given on new parameterisation, coupled models developments, model/data comparison and use of data.

Example of classification method

To classify the different tools we present below an example associated with an instrument. We defined 8 relevant characteristics (see figure below), which combine internal performance, technology, deployment constraints but also economical parameter. Then we obtain an evaluation of the instrument (diagram on the left) for the parameter measured as well as for the instrument considered.

The same exercise will be performed for each instrument/parameter, analytical method, data and models. Combining the results obtained by scale/process investigated will we be able to identify the gaps and the niches of our community.

Note that for instrumentation a technological monitoring will be performed to initiate new instrumental developments and that create an ideal background for collaboration with private companies.
