So, for example, if the spectral extinction coefficient is measured under ambient conditions, the value can be compared with the extinction coefficient measured under controlled RH conditions after calculating the implied hydrated particle properties at ambient RH using the measured RH and particle hygroscopic growth factor.
The example of the ambient spectral extinction coefficient is given in the "Deployment site selection and completion strategies" section above, assuming payload C is flown.
Covering first materials, then energy, with a final section on environmental materials, the 97 papers in this collection explore such topics as extracting volatile oil from a compound recipe of clove and cinnamon using supercritical carbon dioxide, amphiphilic co-networks based on end-group cross-linking of polydimthylsiloxane pentablock copolymer and polymethylhydrosiloxane, a spectral extinction coefficient test of a photoelectric jamming aerosol, the diurnal change model of the instantaneous amount of solar radiation incident on the horizontal surface near the ground, and the efficiency of microbial mutagenesis experiments and the degradation of methane.
Their 30-day pilot study has shown the existence of large, 1km by 1km scale hazy air masses with strongly varying spectral extinction -- a measure for aerosol attenuation to sunlight -- which could be a sign of aerosol pollution, and has demonstrated that the methodology is potentially applicable for daily, global monitoring of aerosols and surface color over cloud-free areas.
