SUMMARY
The discussion centers on using an infrared (IR) camera, specifically a FLIR One, to simulate MODIS (NASA's telescope addon) for detecting gases like CO2. The user seeks a 4µm filter for their camera, which operates in the 8-15µm range, making it unsuitable for CO2 detection. Participants highlight the challenges of using different IR spectrum ranges, noting that various optical materials are required for different wavelengths. The conversation suggests that hyperspectral cameras, typically operating in the visible spectrum, may not meet the user's needs for gas detection.
