We present here a new concept of instrument, based of optical aerosols counter, to better estimate the concentration and size distribution of incoming interplanetary material in the Earth’s atmosphere. This concept, called GRAAL, could be in the Earth’s orbit onboard a micro-satellite or within the International Space Station
