The HD(CP)2 project will explore how different representations of atmospheric processes at their relevant (and usually small) spatial and temporal scales contribute to the overall skill in modeling clouds and precipitation. The observational component HOPE (HD(CP)2 Observational Prototype Experiment) was conducted in spring 2013 to provide input and evaluation data to high resolution (cloud) modeling. Measurements were done at such high resolution that even sub-grid variability in large eddy simulations (LES) can be addressed. By concentrating ground remote sensing instruments with coordinated scanning procedures within a small 10x10km area, HOPE measurements were intended to capture the properties of lower altitude clouds and their environment, especially during the developing stages of clouds and during the onset of precipitation.
The HOPE experiment was conducted from April to June 2013 near Jülich, about 50 km west of Cologne, Germany. Within the 10x10km center area during the experiment, in addition to one permanent site (JOYCE), two temporary sites (HOPE_Krauthausen, HOPE_Hambach) were established. All three sites were equipped with scanning lidar, radar and microwave instruments. In support of the HOPE campaign, the, AERONET group (at NASA-GSFC) provided four Cimel sun-/sky-photometer instruments. Two of the instruments were placed at the two temporary sites (HOPE_Krauthausen, HOPE_Hambach) as an AERONET Cimel is already established at the third (JOYCE) site. This assured RAMAN lidar systems at all three sites were complemented by CIMEL-sun-/sky-photometer sampling. The other two CIMEL instruments were deployed ca. 30km WSW upwind (RTHW_Aachen) and ca. 30km downwind ENE (HOPE_Inselhombroich) of the central facilities, to capture the larger scale (aerosol) variability.
