EAGLE ESA project. Data acquisition report

This document is intended to provide preliminary information about the "data acquisition missions" done during the Eagle campaign over the central part of the Netherlands. The Sky Arrow aircraft operated by the ERALab group of the CNR ISAFoM of Naples (Italy). Measurements in the Planetary boundary layer (PBL) are the main subject for the use of the Sky Arrow Environmental Research Aircraft. The PBL is the part of the atmosphere that is mostly influenced by the earth's surface and so responds to surface forcing with a timescale of less than one hour. Within the PBL the air flow during the day-time can be assumed as permanently turbulent with vertical and horizontal wind components, enabling a transport of heat and gases.With the measurement of temperature, humidity and gas concentrations in the PBL it is possible to calculate latent and heat fluxes, momentum and carbon dioxide fluxes of the underlying surface.Wind components are vital for calculating any atmospheric fluxes as well as the location of the measurement with its specific vegetation and conditions.The document is composed of six section aimed at the description of the platform and it's sensors, and an overview on the "mission plan" followed during the campaign and of measurement results of the flight performed on June 13th.An introduction of the ISAFoM institute mission and on the "Biometeorology" group are given in the Section 2.The Section 3 outlines the aircraft technical specifications.Section 4 gives information about both the in-situ and remote sensing sensors installed on board the aircraft.The mission plan and flights tracks are shown in Section 5, along with main out case of each of the three missions performed.Representation of data from both profiles and flux flights during the first mission are presented in the section 6. Turbulent flux data will be provided in the next report.
