The new Tethered Balloon System Merged (TBSMERGED) data product is available from flights in Oklahoma (above), Texas, Colorado, and Alaska.

The Atmospheric Radiation Measurement (ARM) user facility has a new data product to make it easier for users to work with measurements from its tethered balloon system (TBS) missions.

The TBS normally operates below the lowest cloud base, where it measures temperature, humidity, wind speed, wind direction, turbulence, and aerosol properties. ARM’s new Tethered Balloon System Merged (TBSMERGED) product combines these data sets with ground-based ceilometer data, allowing for examination of cloud-base and boundary-layer heights.

TBSMERGED evaluation data are available from TBS flights at the following ARM sites:

ARM has also produced an in-cloud version of the merged product (TBSMERGEDINCLOUD), which combines the same types of data sets as the standard version but will include measurements of airborne supercooled liquid water content. In-cloud evaluation data are currently available from TBS flights between April 9, 2017, and November 19, 2020, at Oliktok Point, Alaska. Supercooled liquid water content data from Oliktok Point are expected to be available later in 2023.

More information about these data can be found on the TBSMERGED web page.

Access all TBSMERGED data in the ARM Data Center. (Go here to create an account to download the data.)

For questions, feedback, or to report data issues, please contact Dari Dexheimer, ARM’s lead TBS instrument mentor.
