Instrumental equipment carried by the space observatory Aqua

Atmospheric Infrared Sounder (AIRS) It has 2,382 high-resolution channels, 2,378 channels measuring IR radiation in the range 3.7 pm to 15.4 pm, other channels cover visible and near-IR regions (0.4 pm-0.94 pm). 

Advanced Microwave Sounding Unit (AMSU) It is a 15-channel gauge to measure upper atmosphere temperature, radiation in the range 50 GHz to 60 GHz and at frequencies 23.8 GHz, 34.4 GHz, and 89 GHz, water vapor, and precipitation. Spatial resolution of 40 km-45 km. 

Humidity Sounder for Brazil (HSB) HSB is a four-channel microwave device measuring humidity (183.31 GHz) and radiation (150GHz). Horizontal resolution of 13.5 km. 

Clouds and the Earth s Radiant Energy System (CERES) CERES is a broadband three-channel scanning radiometer. One channel measures reflected solar radiation in the range 0.3 pm-5.0 pm. Two other channels (0.3 pm-100 pm and 8 pm-12 pm) measure reflected and emitted radiant energy at the top of the atmosphere. 

Moderate Resolution Imaging Spectro-radiometer (MODIS) MODIS is a 36-channel scanning radiometer in the visible and IR ranges (0.4 pm-14.5 pm), aimed at obtaining biological and physical information about the atmosphere-land system.
