The ATmospheric LIDAR (Light Detection and Ranging), ATLID, is part of the payload of the Earth Cloud, Aerosol and Radiation Explorer (EarthCARE) mission, the sixth Earth Explorer Mission of the European Space Agency (ESA) Living Planet Programme [1]. The EarthCARE payload consists of four instruments that will, in a synergetic manner, retrieve vertical profiles of clouds and aerosols, and the characteristics of the radiative and microphysical properties, to determine flux gradients within the atmosphere and top of atmosphere radiance and flux. ATLID's objective is to provide vertical profiles of optically thin cloud and aerosol layers, as well as the altitude of cloud boundaries. With that purpose ATLID emits

EarthCARE, the Earth Cloud Aerosol and Radiation Explorer, is the third Earth Explorer Core Mission of the European Space Agency's Earth Observation Envelope Programme. These are defined as major missions led by ESA to cover primary research objectives set out in the Living Planet Program. EarthCARE is being developed in cooperation with the Japan Aerospace Exploration Agency (JAXA), which is providing the Cloud Profiling Radar.

Since the eighties, several French organizations (Ifremer, CNRS, and marines universities) have joined their forces to operate the first high frequency automated network around France. Now days, 14 Instrumented platforms are in operation along the North Sea, the Atlantic and Mediterranean French coasts. Furthermore, this organization is now largely contributing to the French national Research Infrastructure named "I.R. ILICO".

Direct spectral clustering framework was first proposed to extract general pattern events within multivariate time series. This study investigated the way to identify extreme events, i.e. short duration and/or particular events, with no assumption about their emission date, duration and/or shape. A Multilevel Spectral Clustering (Μ-SC) architecture is proposed and compared with state-of-the-art clustering methods from a simulated manually labeled time series. Due to these promising empirical results, this new deep architecture is applied on marine field data.

The Earth Explorer Core Missions are an element of the European Space Agency Earth Observation Envelope Programme. They are defined as major missions led by ESA to cover primary research objectives set out in the Living Planet Program. EarthCARE, the Earth Clouds Aerosols and Radiation Explorer, has been selected for implementation as the third Earth Explorer Core Mission and is being developed in cooperation with the Japan Aerospace Exploration Agency (JAXA) who provides one of the active instruments. The fundamental objective of EarthCARE is to improve the understanding of the processes involving clouds, aerosols and radiation in the Earth's atmosphere. In order to fulfill this objective, the EarthCARE payload is composed of four instruments, a High Spectral Resolution UV ATmospheric LIDar (ATLID), a 94GHz Cloud Profiling Radar (CPR) with Doppler capability, a Multi-Spectral Imager (MSI) and a Broad-Band Radiometer (BBR). The four instruments will provide, in a synergetic manner, information on cloud and aerosol vertical structure of the atmosphere along the satellite track as well as information about the horizontal structures of clouds and radiant flux from sub-satellite cells. All the four EarthCARE instruments are now approaching their final development stages and are all scheduled to be delivered for integration into the satellite platform in 2018.

The paper deals with a monitoring system combining K-means classifier and one Hidden Markov Model in order to detect phytoplankton blooms and to understand their dynamics. The states of the Hidden Markov Model and codebook symbols are computed without a priori knowledge thanks to K-means algorithms. The system is tested on database signals from the Marel-Carnot station that registers water characteristics at high frequency resolution. The experiments show that, when the states are set to two, these correspond to phytoplankton productive and non-productive periods. Moreover, when states are set to five, these correspond to the dynamics of phytoplankton blooms.

The earth clouds, aerosols, and radiation explorer mission has been selected as the 6th earth explorer mission of ESA's living planet programme [1]. A suite of four instruments, active and passive, will be embarked on the same satellite to measure cloud and aerosol properties simultaneously with TOA radiances in order to derive TOA fluxes in relation to clouds and aerosols.
