Dataset Name

Dataset Name - The name of the GOES-SST data set archived at CLASS. There are five different naming formats as below:

1. Data-Type_Year_Day_Hour with each qualifier defined below:

Qualifier Details

Data-Type

Four or five characters identifying the data type. Recognized character groups are:

match1 = GOES Hourly SST Matchup

Year Full year with century, e.g., 2005, which identifies the year in which the spacecraft began recording the data.
Day Day of the year [001-366], which identifies the Julian day on which the spacecraft began recording the data.
Hour e.g. 13, where "13" denotes 13 hours UTC (to the nearest hour) and represents the time at which spacecraft recording began.

Temporal

Refers to the time span of interest to the user. This section of the search page allows the user to define the range of dates/times of interest.

Back to the top

Time

The UTC date and time corresponding to the beginning of the coverage of the given dataset. Format is yyyy-mm-dd hh:mm:ss.fff where fff is the fraction of a second in milliseconds.

UTC

Coordinated Universal Time (UTC) is the international time standard. It is the current term for what was referred to as Greenwich Meridian Time (GMT). Zero (0) hours UTC is midnight in Greenwich England, which lies on the zero longitudinal meridian. Universal time is based on a 24 hour clock, therefore, afternoon hours such as 4 pm UTC are expressed as 16:00 UTC (sixteen hours, zero minutes).
