Dataset Name

The name of the CoastWatch data set archived at CLASS. There are two different naming formats used for these files:

• CoastWatch-RegionYearDayStart-Time.CoastWatch-SubregionProduct-Type with each qualifier defined below:

Qualifier	Details
CoastWatch-Region	One character identifying the CoastWatch Region to which this data applies. Valid character is: c = Caribbean
Year	Last two digits of the year (99 = 1999, 00 = 2000), which identifies the year in which the spacecraft began recording the data set.
Day	Day of the year [001-366], which identifies the Julian day on which the spacecraft began recording the data set.
Start-time	e.g. 13, where "13" denotes 13 hours UTC (to the nearest hour) and represents the time at which spacecraft recording began.
CoastWatch-Subregion	One character identifying sub-regions within the CoastWatch region to which data pertains. Valid sub-region characters are: p = Puerto Rico high resolution j = Jamaica high resolution
Datatype	Two characters identifying codes for the types of products. Valid character groups are: c2 = AVHRR channel 2 albedo (%) c4 = AVHRR channel 4 brightness temperature (deg C) cm = cloud mask d7 = daytime split-window non-linear sea-surface-temperature (c4 and c5) s3 = nighttime triple-window multi-channel sea-surface-temperature (c3, c4, c5) s7 = nighttime split-window non-linear sea-surface-temperature (c4 and c5) s9 = nighttime triple-window non-linear sea-surface-temperature (c3, c4, c5) sm = nighttime multiple sea-surface-temperature algorithm

• Year_Day_Start-Time_Spacecraft-Unique-ID_CoastWatch-RegionCoastWatchSubregion_Product-Type. File-Format with each qualifier defined below:

Qualifier	Details
Year	Full year with century, e.g., 2005, which identifies the year in which the spacecraft began recording the data set.
Day	Day of the year [001-366], which identifies the Julian day on which the spacecraft began recording the data set.
Start-Time	e.g. 1355, where "1355" denotes 13 hours 55 minutes UTC (to the nearest minute) and represents the time at which spacecraft recording began.
Spacecraft-Unique-ID	n15 = NOAA-15 (NOAA-K) n16 = NOAA-16 (NOAA-L) n17 = NOAA-17 (NOAA-M)
CoastWatch-Region	One character identifying CoastWatch Region to which this data applies. Valid characters is: c = Caribbean
CoastWatch-Subregion	One or two characters identifying sub-regions within the CoastWatch region to which the data pertains. Valid sub-region characters are: p = Puerto Rico high resolution j = Jamaica high resolution bz = Belize cj = Cuba/Jamaica synoptic ec = East Caribbean synoptic eg = East Gulf of Mexico synoptic fk = Florida Keys gp = Gulf of Papayayo synoptic gt = Gulf of Tehuantepec synoptic nf = Northern Florida sa = San Andreas Bight synoptic wg = West Gulf of Mexico synoptic yc = Yucatan Channel bh = Bahamas dh = Dominican Rep/Haiti synoptic fb = Flower Garden Banks gr = Grays Reef la = Lesser Antilles synoptic mm = Mazatlan/Mexico synoptic pc = Panama/W. Columbia synoptic vc = Venezuala/Columbia synoptic wc = West Caribbean synoptic xs = Full Regional panel (2.5 km) xx = Full Regional panel (10 km) yp = Yucatan Peninsula synoptic
Product-Type	Two characters identifying codes for the types of products. Valid character groups are: c2 = AVHRR channel 2 albedo (%) c4 = AVHRR channel 4 brightness temperature (deg C)cm = cloud mask d7 = daytime split-window non-linear sea-surface-temperature (c4 and c5) s3 = nighttime triple-window multi-channel sea-surface-temperature (c3, c4, c5) s7 = nighttime split-window non-linear sea-surface-temperature (c4 and c5) s9 = nighttime triple-window non-linear sea-surface-temperature (c3, c4, c5) sm = nighttime multiple sea-surface-temperature algorithm

Time

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).
