 (Translation: ocean and cloud observation - the trans-ITCZ experiment)

+
+The goal of BOW-TIE is to investigate how processes on the scale of convective storms, and their interaction with the ocean, impact the properties of the Atlantic Intertropical Convergence Zone (ITCZ). Focusing on storm-scale processes is motivated by current research which suggests their crucial role for the mesoscale dynamics in the ITCZ which in turn appears important for understanding its large-scale structure and subsequent links to global circulation patterns.
+
+To link the storm-scale processes to the large-scale ITCZ ship-board measurements are used, with repeated crossings of the ITCZ, linking detailed vertical profiling of the atmosphere and ocean to long-standing buoy measurements through the PIRATA array. This pattern will have weak sea-surface temperature gradients for the western and strong gradients for the eastern leg.
+
+Important tasks will be to obtain vertically resolved cross-sections of the ITCZ, through the upper ocean, and the surrounding thermodynamic and dynamic conditions. Measurements will include atmospheric and oceanic measurements, with more intensive measurements of the ocean and atmosphere boundary layers; these will allow us to also investigate the atmosphere-ocean coupling on the scale of the storm systems.
+
+Main measurements will include precipitation, cloud profiles, humidity profiles, wind profiles, surface wind speeds and direction, sea-surface temperature and upper ocean measurements of temperature, currents speed and direction, and salinity. As a related component, the campaign will explore cloud
+microphysical development and aerosol-cloud interactions in the exceptionally clean conditions of the inner ITCZ, as these are thought to influence the surface energy budget and hence air-sea coupling. Together these measurements will provide a benchmark for storm-resolving models and help to determine why they lead to an improved representation of the tropical circulation systems.

 MAESTRO is a French initiative that uses the French research aircraft SAFIRE ATR-42 and is funded by the European Research Council (ERC).
-The MAESTRO campaign will take place from 10 August to 10 September 2024 over the Atlantic ocean near Cape Verde, with research aircraft operating out of Sal (16o4’N, 22o6’W).
 
-Details on the science, flight strategy and instrumentation is available from the [official MAESTRO website](https://maestro.aeris-data.fr/).
+The project aims to answer this question by addressing the following goals:
+
+* Unravel the physical processes that control the mesoscale organisation of shallow and deep convection over tropical ocean
+* Understand how the organisation of convection impacts the Earth’s radiation budget through water vapour and clouds
+* Assess the ability of the new emerging climate models to predict the interplay between the mesoscale organisation of convection and climate
+
+As part of this project, an airborne field campaign will be organized to collect the observations needed to test mechanisms hypothesized to control the mesoscale organisation of shallow and deep convection and to assess the quality of the new EarthCARE satellite observations.

+PERCUSION is a German initiative that uses the German research aircraft [HALO](https://halo-research.de) and ESA's [EarthCARE](https://earth.esa.int/eogateway/missions/earthcare) satellite aiming to test factors hypothesized to influence the organization of deep maritime convection in the tropics, and the influence of convective organization on its larger-scale environment.
+PERCUSION will extend the NARVAL missions and EUREC4A cases to missing convective (and aerosol) regimes and contribute to a broader view of cloud-circulation coupling over the tropical oceans. PERCUSION will add a new dimension to the previous measurements through it’s
+
+Focus on deep convection close to and at the Intertropical Convergence Zone. This will complement the EUREC4A measurements, which have focused on the winter downstream trade-wind regimes and provide a more comprehensive picture of the tropical circulation.
+Studying the impact of different aerosol regimes. HALO will operate three weeks in the western (42W-60W) tropical Atlantic flying out of Barbados, and three weeks in the eastern (25W-43W) flying out of Cape Verde, respectively. This will contrast clouds and circulation in relatively particulate-free air, or in aged dust layers, in the west, with air masses with large (Saharan) dust burdens in the east.
+Towards a global coverage by locally validating EarthCARE. The upcoming EarthCARE satellite will become a spaceborne cloud observatory and will enable us to extend local studies to globa al scale. To establish confidence in EarthCARE products and inform their most intelligent use, we will intensively use HALO underflights for validation purposes.
