A laboratory assessment of the Waveband Integrated Bioaerosol Sensor (WIBS-4) using individual samples of pollen and fungal spore material

► A laboratory assessment of the WIBS-4 bioaerosol sensor for PBAP discrimination. ► Multiparameter optical signatures of in-flight pollen and fungal spore are measured. ► Aspergillus fumigatus gives a signature which could be used for field detection.
