CALIPSO Total Attenuated Backscatter

The CALIPSO lidar level 1.5 data product contains profiles of attenuated backscatter and aerosol extinction coefficients for which clouds, overcast, surface, subsurface, and totally attenuated samples have been removed before being averaged to a 20 km horizontal resolution. The new V1.00 standard level 1.5 product is based entirely on version 4 CALIOP data, thus providing accurately calibrated attenuated backscatter coefficients and the benefits of the most sophisticated CALIOP scene classification algorithms.

NASA Instruments Image Fireball over Bering Sea

NASA Instruments Image Fireball over Bering Sea

On Dec. 18, 2018, a large "fireball" - the term used for exceptionally bright meteors that are visible over a wide area - exploded about 16 miles (26 kilometers) above the Bering Sea. The explosion unleashed an estimated 173 kilotons of energy, or more than 10 times the energy of the atomic bomb blast over Hiroshima during World War II. It was the most powerful meteor to be observed since 2013; however, given its altitude and the remote area over which it occurred, the object posed no threat to anyone on the ground.

SAGE III-ISS Occultation Event

SAGE III-ISS Occultation Event

This moonset image is illustrating an occultation event from the SAGE III instrument, which is used to measure Ozone, NO2 and NO3 concentrations in the upper atmosphere. Nitrogen Trioxide (NO3) virtually disappears from the atmosphere when the sun rises, but SAGE III/ISS utilizes lunar occultation to measure its concentration. Version 5.1 is the first official release of SAGE III/SS data that includes provisional products suitable for use in both validation and research studies and some new beta data products.

MOPITT Imagery for California Fires
The Measurement of Pollution in the Troposphere (MOPITT) instrument is flying on board NASA's Terra satellite. It observes CO in the troposphere through thermal and near infrared channels.The imagery clearly shows enhanced levels of CO associated with the Camp and Woolsey wildfires in northern and southern California, respectively. The high CO west of Mexico may be an aged part of the Woolsey/Camp plumes, based on the location of high CO the day before and on the smoke trajectories shown by the MODIS visible images.

CALIPSO and CloudSat over Typhoon Yutu
Typhoon Yutu near the coast of Japan on October 28, 2018. Data from the CALIPSO lidar and CloudSat radar appear as vertical slices in the atmosphere. CALIPSO lidar data is visualized as a bluish slice, with red and yellow colors denoting more scattering off of clouds and aerosols. CloudSat radar data is superimposed on the CALIPSO slice in brighter colors.
