Google Earth Engine ——MYD13Q1.006 Aqua Vegetation Indices 16-Day Global 250m分辨率(NDVI/EVI)数据集

The MYD13Q1 V6 product provides a Vegetation Index (VI) value at a per pixel basis. There are two primary vegetation layers. The first is the Normalized Difference Vegetation Index (NDVI) which is referred to as the continuity index to the existing National Oceanic and Atmospheric Administration-Advanced Very High Resolution Radiometer (NOAA-AVHRR) derived NDVI. The second vegetation layer is the Enhanced Vegetation Index (EVI) that minimizes canopy background variations and maintains sensitivity over dense vegetation conditions. The EVI also uses the blue band to remove residual atmosphere contamination caused by smoke and sub-pixel thin cloud clouds. The MODIS NDVI and EVI products are computed from atmospherically corrected bi-directional surface reflectances that have been masked for water, clouds, heavy aerosols, and cloud shadows.

Google Earth Engine——AVHRR探路者5.3版海面温度数据集(PFV53)是由NOAA国家海洋学数据中心和迈阿密大学罗森斯蒂尔海洋与大气科学学院合作制作的全球每日两次的4公里数据

The AVHRR Pathfinder Version 5.3 Sea Surface Temperature dataset (PFV53) is a collection of global, twice-daily 4km sea surface temperature data produced in a partnership by the NOAA National Oceanographic Data Center and the University of Miami's Rosenstiel School of Marine and Atmospheric Science. PFV53 was computed from data from the AVHRR instruments on board NOAA's polar orbiting satellite series using an entirely modernized system based on SeaDAS. PFV53 data are nearly 100% compliant with the GHRSST Data Specification Version 2.0 for L3C products and only deviate from that standard in that 'sses_bias', 'sses_standard_deviation', and 'sst_dtime' variables are empty and hence not included into EE assets. PFV53 data were collected through the operational periods of the NOAA-7 through NOAA-19 Polar Operational Environmental Satellites (POES), and are available from 1981 to 2014. Additional information is available at the [NOAA Pathfinder site] (NODC Pathfinder SST Data).
