Cloud Type<\/h1>\n

Operationally produced by NWC SAF.<\/p>\n

\n

Application:<\/h2>\n

Identification of cloudy and cloud free areas.<\/p>\n

Detection of the presence of snowy grounds.<\/p>\n

Identification of major cloud classes (low broken (fractional), high semi-transparent, high, mid-level and low thick clouds).<\/p>\n

Advantages:<\/h2>\n

\u2713 Available from meteorological geostationary satellites (GOES, Himawari, MSG).<\/span><\/p>\n

\u2713 Available during day and night.<\/span><\/p>\n

\u2713 Available at the temporal frequency of the satellites.<\/span><\/p>\n

Limitations:<\/h2>\n

X Low clouds may not be detected at low sun elevation or even at night-time (infrequent).<\/span><\/p>\n

X Snow is not identified at night-time and may be confused as low clouds.<\/span><\/p>\n

X Low clouds surmounted by thin cirrus may be classified as mid-level clouds.<\/span><\/p>\n

X Very low clouds may be classified as mid-level clouds in case strong thermal inversion.<\/span><\/p>\n

X Very thin cirrus may be classified as low broken clouds.<\/span><\/p>\n<\/div><\/div>\n
