Optical fiber sensors drawn from polyurethane are demonstrated. Polyurethane’s Young’s Modulus is orders of magnitude lower than traditional optical fiber materials, permitting more sensitive optical detection of mechanical perturbations.

The look-up table algorithm is studied to retrieve vertical profile of aerosol extinction based on measured the O4 of multi-elevation angles with MAX-DOAS. The retrieved aerosol extinction in boundary layer is compared with PM2.5 data measured by ground point instrument. The results show that the look-up table method can obtain the aerosol state of the troposphere and provide validation for other instrument.
