To provide a device for measuring mass concentration of solids, such as volcanic ash and ice crystals, suspended in the remote air ahead of an aircraft during flight.SOLUTION: An air suspended solid mass concentration measurement lidar is provided, comprising a lidar configured to measure the backscattering intensity of solids suspended in the remote air using a laser beam of one wavelength, and a mass concentration converter configured to convert the backscattering intensity into mass concentration in the vicinity of a preset mass concentration on the basis of a particle size dominant for the backscattering intensity of the solids.SELECTED DRAWING: Figure 1

    【課題】航空機が飛行中に前方の火山灰や氷晶等の遠隔の大気中に浮遊する物質の質量濃度を計測する装置を提供する。【解決手段】大気浮遊物質質量濃度計測ライダーは、一波長のレーザ光を用いて遠隔の大気中に浮遊する物質の後方散乱強度を計測するライダーと、前記物質の後方散乱強度に支配的な粒径に基づき、あらかじめ設定した質量濃度の近傍において前記後方散乱強度を質量濃度に換算する質量濃度換算器とを具備する。【選択図】図1
