Title(s):Main Title: JOYCE: Jülich Observatory for Cloud Evolution
Description(s):Abstract: The Jülich Observatory for Cloud Evolution (JOYCE), located at Forschungszentrum Jülich in the most western part of Germany, is a recently established platform for cloud research. The main objective of JOYCE is to provide observations, which improve our understanding of the cloudy boundary layer in a mid-latitude environment. Continuous and temporally highly resolved measurements that are specifically suited to characterize the diurnal cycle of water vapor, stability and turbulence in the lower troposphere are performed with a special focus on atmosphere-surface interaction. In addition, instruments are set up to measure the micro- and macro-physical properties of clouds in detail and how they interact with different boundary layer processes and the large-scale synoptic situation. For this, JOYCE is equipped with an array of state-of-the-art active and passive remote sensing and in-situ instruments, which are briefly described in this scientific overview. As an example, a 24h time series of the evolution of a typical cumulus cloud-topped boundary layer is analyzed with respect to stability, turbulence and cloud properties. Additionally, we present longer-term statistics, which can be used to elucidate the diurnal cycle of water vapor, drizzle formation through autoconversion and warm versus cold rain precipitation formation. Both case studies and long-term observations are important for improving the representation of clouds in climate and numerical weather prediction models.
