High Resolution Water Vapour Winds - MFG - 0 degree

Vectors are derived by tracking the motion of clouds in the Meteosat First Generation (MFG) WV channel. It uses a slightly different algorithm compared to the MFG IR vector product (ELW), namely the FFT surface correlation method. It uses the high resolution MFG matrix with 16 x 16 pixel segments, i.e. the same product resolution as the HRV product, but MFG WV image data is still low resolution. A typical HWW product contains about 5000 VW vectors.本数据集的矢量数据通过追踪静止气象卫星第一代（Meteosat First Generation, MFG）水汽（Water Vapor, WV）通道内的云运动生成。其采用的算法与MFG红外矢量产品（ELW）存在细微差异，具体使用快速傅里叶变换（Fast Fourier Transform, FFT）表面相关法。该算法采用分辨率为16×16像素区块的高分辨率MFG矩阵，其产品分辨率与高分辨率可见光（High Resolution Visible, HRV）产品一致，但MFG WV图像数据仍为低分辨率。典型的HWW产品包含约5000个VW矢量。
