From undergoing an orbit lowering to headlining workshops on novel drifting data, Terra has had a big year so far! (And that’s not even accounting for the satellite’s continuous collection of high quality, earth science data, with no unintended interruptions!)
This news post will provide several important updates on recent instrument team meetings, upcoming virtual workshops featuring Terra, and an overview of three early career scientists using Terra data in their research.

2022 Meetings and Conferences
The CERES instrument team participated in the Fall 2022 Earth Radiation Budget Workshop in Hamburg, Germany from October 12 – 14, 2022. More information, including an agenda and presentation slide decks, can be found on the CERES website.
Several members of the Terra team participated in the 22nd William T. Pecora Memorial Remote Sensing Symposium in Denver, CO from October 23 – 28, 2022. More information available on the Pecora 22 website.
The ASTER instrument team will hold a science and interface meeting in Tokyo, Japan from November 7-9, 2022.
The American Geophysical Union (AGU) Fall 2022 meeting will be held in Chicago, IL from December 12 – 16, 2022. For more information and an agenda, visit the AGU Fall Meeting 2022 website.
On December 8th, 2022 from 12:30 PM – 3:30 PM ET, the Terra team will be hosting a virtual community forum on Terra’s recent orbit lowering maneuvers (that took place October 12th and 18th). See the graphic below for more information and a QR code linking directly to the Webex webinar registration page.
Highlighting Two Decades of Terra Talent
Last week, several NASA Early Career researchers presented their current scientific work during the 2022 Early Career Scientist Forum (full agenda linked here).
Explosive Volcanic Eruption Dynamics
Kathleen incorporates data from Terra’s Multi-Angle Imaging Spectroradiometer (MISR) instrument to analyze volcanic ash and aerosols throughout the atmospheric column.
Andy uses satellite products, like the Normalized Difference Vegetation Index from the Moderate Resolution Imaging Spectroradiometer (MODIS), to analyze how changes in precipitation intensity and frequency impacts plant photosynthesis.
The Terra Flight Operations Team is planning a set of orbital maneuvers for October 12 and 19 to lower Terra’s orbit by 6 km, as part of an effort to reduce orbital crossings with several other missions currently at Terra’s 705 km altitude. For more information, view the animation and graphic below, which are also available on the Terra website.
Summer is in full swing, but it wouldn’t be complete without a visit to “camp”.. Camp Landsat, that is!
“Terra Visits Camp Landsat” is part story map, part interactive virtual series, highlighting the weekly themes of Camp Landsat 2022. Check out our Week 1: People and Placesstory map below, focused on Black Rock City — a massive urban area that only exists for one week out of the year, during the annual Burning Man event. View the full screen version by clicking on the icon above (and for a challenge, see if you can find the ceremonial “burning-of-the-man” fire signature in satellite data!)

We recently featured several important scientists who use Terra data in their research, including Dr. Rebecca Buchholz (check out the post here) who works with Dr. Helen Worden, the US Principal Investigator for the Measurements of Pollution in the Troposphere (MOPITT) sensor to evaluate spatial patterns of air pollution critical for natural hazard response and public health planning.
MOPITT data are used to derive carbon monoxide concentrations such as those released from burning vegetation, coal, and other combustible plant material. MOPITT carbon monoxide measurements are used to determine where wildfires are burning and to infer the presence of other air pollutants, too. After analyzing over 15 years of data, the MOPITT team found that overall carbon monoxide levels have decreased globally over the past decade, but with varying amounts related to regional land use differences. Additionally, the team also discovered that an increase in new seasonal peaks of air pollution– especially from summer wildfires burning in the American Pacific Northwest – contribute to increased health risks “downwind” of these fires – even impacting places as far away as Colorado!
