MLS/Aura Level 2 Cloud Top Pressure V006 (ML2CTP)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/aura/mls/data2623
ML2CTP is the EOS Aura Microwave Limb Sounder (MLS) standard product for cloud top pressure derived from radiances centered at 190, 250 and 640 GHz radiometers.
Description
The data version is 6.0. Data coverage is from August 8, 2004 to current.
Spatial coverage is near-global (-82 degrees to +82 degrees latitude), with each profile spaced 1.5 degrees or ~165 km along the orbit track (roughly 15 orbits per day). The recommended useful vertical range is between 770 and 85 hPa, and the vertical resolution varies between ~3.6 and 6 km. Users of the ML2CTP data product should read section 3.7 of the EOS MLS Level 2 Version 6 Quality Document for more information.

The data are stored in the version 5 EOS Hierarchical Data Format (HDF-EOS5), which is based on the version 5 Hierarchical Data Format, or HDF-5. Each file contains two swath objects (profile and column data), each with a set of data and geolocation fields, swath attributes, and metadata.
