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 (UPV/EHU).

The community workshop on infrared emissivity measurement returns. Founded in 2024 and first organized by the Thermomat / HAIRL group at UPV/EHU in Bilbao, IR-EMPOWER brings together the laboratories of the research map — metrology institutes, high-temperature facilities, and university groups — around measurement below and above 1000 K. Registration is open; poster abstracts are due 31 July 2026.

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.
| Institution | Country | Tier | Representative capability |
|---|---|---|---|
| Physikalisch-Technische Bundesanstalt Working Group 7.35 — Emissivity | DE | core | Traceable spectral emissivity, −40 °C to ≈2300 °C, air and vacuum, near to far infrared. |
| CEMHTI — CNRS High-temperature radiative properties, Orléans | FR | core | Spectral emissivity of ceramics, glasses, and refractories above 1500 K. |
| DLR Institute of Planetary Research Planetary Spectroscopy Laboratory, Berlin | DE | core | Vacuum FTIR emissivity 0.3 to >100 µm, heated planetary-analog samples; Berlin Emissivity Database. |
| Thermomat / HAIRL — UPV/EHU Thermophysical properties group, Bilbao | ES | core | FTIR directional spectral emissometry with uncertainty budget; maintainers of EKHI. |
| PROMES — CNRS Solar furnace facilities, Odeillo | FR | core | High-temperature radiative properties under concentrated solar flux; selective absorbers. |
| National Institute of Standards and Technology Infrared radiometry and emittance metrology | US | core | Infrared spectral emittance, radiance temperature, and radiometric standards. |
| Stanford University Fan Group — Ginzton Laboratory | US | engineered | Radiative sky cooling; nanophotonic control of spectral and directional thermal emission. |
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.
Definitions, directional and spectral quantities, and why a single "ε value" is rarely enough.
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.
