A nonlinear spectral resolved imaging technique based on two-photon excited fluorescence (TPEF) and second-harmonic generation (SHG) combines the advantages of two-photon microscopy with that of spectral measurement technique.

The Application Prospect of Moderate-resolution Imaging Spectroradiometer(MODIS)Data in Earth Science;

For its high spectral and time resolution, MODIS data was more suitable for the inversion of snow depth compared to NOAA and other remotely sensed data.

The objective of this paper is to determine the suitable MODIS spectral indices for monitoring growth status change during crop growing season.

Based on 8-year(March 2000-February 2008) MODIS satellite data,the spatial and temporal distributions of aerosol optical depth(AOD) and fraction of fine-mode aerosols(FMF) were examined over the Beijing-Tianjin-Hebei plain area.

For the visible and infrared radiometer (VIRR) infrared 4-channel and medium resolution spectral imager(MERSI) infrared 5-channel,the line-by-line radiative transfer model (LBLRTM),in which the atmospheric profiles adopt global 52 atmospheric profiles generated by ECMWF,was performed to calculate the spectral radiance emitted from the earth-atmosphere between 8μm and 14μm.
