Abstract:
ML2O3_NRT is the EOS Aura Microwave Limb Sounder (MLS) Near-Real-Time (NRT) product for ozone (O3). This product contains daily O3 profiles taken from the 240 GHz band. The most recent 7 days of data are available. Spatial coverage is near-global (-82° to +82° latitude), with each profile spaced 1.5° or ~165 km along the orbit track (roughly 15 orbits per day). The recommended useful vertical ... range of NRT Ozone profiles is 68-0.2 hPa, except for the calculation of ozone columns where the 100 hPa pressure level may be used. There are about 96 NRT files per day containing roughly 15 minutes or less of data each.
Before using these data, please download both the MLS version 2.2 NRT User Guide which describes the NRT algorithm and data quality, as well as the MLS Level-2 Data Quality Document for Standard Products which describes the caveats for using MLS O3 data. MLS documentation can be found at http://disc.sci.gsfc.nasa.gov/Aura/additional/documentation/.

Quality
Dates provided in temporal coverage are approximate only, and correspond to the beginning of the Heard Island expeditions, and the end of the Macquarie Island expeditions in the 2000/2001 season.
Access Constraints
These data are not yet publicly available.
An excel spreadsheet detailing which species were collected, an approximate location, the collectors name, whether the plant is still alive in the Royal Tasmanian Botanical Gardens, and their accession numbers at the RTBG is available for download at the URL given below. A word document with some propagation information is also available.
