The Dataset's Variables and Attributes

Row Type	Variable Name	Attribute Name	Data Type	Value
attribute	NC_GLOBAL	_NCProperties	String	version=1\|netcdflibversion=4.6.1\|hdf5libversion=1.10.1
attribute	NC_GLOBAL	acknowledgement	String	This product supported by the Board of Public Utilities.
attribute	NC_GLOBAL	cdm_data_type	String	Grid
attribute	NC_GLOBAL	comment	String	Timestamps with data provided in 'composite_start_time' and 'composite_end_time' define daylight hours as all data within that time window. Timestamps with data provided in 'minimum_sun_angle' defined daylight on a pixel-by-pixel basis dependent on the sun angle at that point and time. Data is regridded to a subset of the MUR SST grid.

attribute	NC_GLOBAL	summary	String	This product is a daily coldest pixel composite using NOAA-Advanced Very High Resolution Radiometer (AVHRR) satellite Sea Surface Temperature (SST) declouded based on reflectivity in the visible spectrum. This method of declouding is limited to daylight hours, but lets in cold water that often gets flagged as clouds based on other declouding algorithms, making this product a useful tool for identifying upwelling regions and storm cooling earlier than they are typically seen in other SST products.
