It maintains the research map of the field, indexes its open data resources, documents measurement standards and good practice, and keeps the community calendar. Editorially maintained by the community; hosted at the University of the Basque Country (EHU).
Dr Jean-Baptiste Perrin-Terrin has defended his doctoral thesis at CentraleSupélec on plasma-assisted combustion in low-emission burners, work funded by the ERC GreenBlue project. The defence was announced through the TAMARYS research network, which emissivity.org reports with the agreement of its coordination.

The programme is out: 21 talks over two days at the Center for Applied Energy Research, from national metrology institutes to university groups, with plenaries by EHU and LTeN-CNRS, a laboratory tour, two poster sessions, a round table on the future of the community and the Young Speaker Award. Founded in 2024 by the Thermomat / HAIRL group at EHU, IR-EMPOWER is the one meeting devoted entirely to emissivity measurement.

About forty researchers are meeting at the Center for Applied Energy Research in Würzburg for two days of talks, posters and a laboratory tour devoted to infrared emissivity measurement. The round table and the Young Speaker Award close the workshop on Tuesday afternoon.
Twenty-one talks, two poster sessions and a round table on how the community should grow: the second IR-EMPOWER is now part of the series archive, alongside the 2024 Bilbao edition.
A curated directory of the non-commercial institutions where emissivity and thermal radiative properties are actively researched — from national metrology institutes to planetary spectroscopy and engineered thermal emission. Inclusion criteria, tier logic, and limitations are documented in the methodology. Last revision: 2026-06.

The field's openly accessible databases of radiative and optical property data, each maintained by a member institution. Counts are exact and dated; every dataset is traceable to its source publication.
Direct radiometric emissometry, indirect reflectance methods, calorimetry — with their uncertainty budgets.
ISO and ASTM standards, the CCT-S1 international comparison, and community good-practice guides.
Non-contact thermometry, spacecraft thermal control, radiative cooling, remote sensing, energy systems.
The map, the calendar, and the bibliography are maintained by the community they describe.
If your laboratory belongs on the research map, if you have published data that should be indexed, or if you are organizing a meeting the community should know about — write to the editorial board. Inclusion follows the published methodology; every entry is verified against public institutional sources before it goes live.
