Aerosol datasets over the Tibetan Plateau (2006-2019)- A Big Earth Data Platform for Three Poles

There are two types of aerosol data in the Tibetan Plateau.

Aerosol type data products are the results of aerosol type data fusion by using Meera 2 assimilation data and active satellite CALIPSO products through a series of data preprocessing, quality control, statistical analysis and comparative analysis. The key of the algorithm is to judge the CALIPSO aerosol type. According to CALIPSO aerosol types and quality control, and referring to merra 2 aerosol types, the final aerosol type data (12 kinds) and quality control results were obtained. Considering the vertical and spatial distribution of aerosols, it has high spatial resolution (0.625 ° × 0.5 °) and temporal resolution (month).

Aerosol optical depth (AOD) is a visible band remote sensing inversion method developed by ourselves, combined with merra-2 model data and NASA's official product mod04. The data coverage time is from 2000 to 2019, with daily temporal resolution and spatial resolution of 0.1 degree. The retrieval method mainly uses the self-developed APRs algorithm to retrieve the aerosol optical depth over the ice and snow. The algorithm takes into account the BRDF characteristics of the ice and snow surface, and is suitable for the inversion of aerosol optical thickness on the ice and snow. The results show that the relative deviation of the data is less than 35%, which can effectively improve the coverage and accuracy of the polar AOD.

File naming and required software

File name: the data is stored in HDF grid format, and the file name is yyyy_ ddd_ Daily_ Mosiac_ APRS_ Mod04.hdf, where yyyy stands for year and DDD stands for date, such as 2000_ 061_ Daily_ Mosiac_ APRS_ Mod04.hdf description of sol optical thickness in the 61st weather in 2000
Data reading method: it can be opened by ArcGIS software and program, and the main grid value represents aerosol optical thickness and aerosol type.
