| Many atmospheric probes are placed on spacecraft and sent into outer space to send back information on the atmospheric conditions of other planets including Venus and Mars. On Earth, many experiments are carried out on planes that have been fitted with various instruments to measure different atmospheric conditions and climatic changes. | |

The ARAT experiment was carried out in
France using the French atmospheric research aircraft (F-27/ARAT). The
objectives of this experiment were to perform microphysical and optical
measurements in cumuliform/stratiform clouds in order to sample different
kinds of cloud particles (water droplets, drizzle, ice crystals, mixed-phase
particles, ...). |

| The AEROCONTRAIL project was aimed at a better understanding of the effect of aircraft exhaust on contrail and aerosol formation and of their impact on the climate. This project included the combination of ground-based observations, aircraft in situ observations (DLR-Falcon aircraft) and numerical modeling. |

The CIRRUS experiment was devoted to
obtaining microphysical and optical properties of cirrus clouds with
radiation measurements. These measurements were obtained with the
airborne Infrared Cryogenic Spectrometer (SICAP) designed and developed by
ONERA. |

| Intensive aircraft field observations of clouds and radiation was carried out by the Meteorological Research Institute (MRI, Tsukuba) within the Japanese Cloud and Climate Study (JACCS) program. The experimental strategy was designed to simultaneously document the radiative and microphysical properties of winter-time boundary-layer clouds, including mixed-phase situations, by synchronized formation flights with two aircraft. |

| Odin is a small, low cost satellite that uses sub-mm techniques to perform both atmospherical and astronomical studies. The main scientific goal of the Odin project is to explore the middle and upper atmosphere and interstellar medium using new areas of the spectrum. The instruments used are a radiometer called SMR (Sub Millimeter Receiver) and an optical instrument called OSIRIS (Optical Spectrometer and InfraRed Imaging System). |
