Gradient in X- Direction - Change in optical thickness in the negative direction along the X axis.
Gradient in X+ Direction - Change in optical thickness between the grid point and neighbor points within the field in the positive direction along the X axis.
Gradient in Y- Direction - Change in optical thickness in the negative direction along the Y axis.
Gradient in Y+ Direction - Change in optical thickness in the positive direction along the Y axis.
Average Gradient - The average of the gradients in all four directions (N, S, E, W) from the grid intersection.
Climatological Temperature - The average sea surface temperature of a grid intersection for a particular month over a number of years, taken from the global climatology file.
Spatial Covariance X- - The distance in grid units from the grid intersection to the nearest land mass in the negative direction along the X axis.
Spatial Covariance X+ - The distance in grid units from the grid intersection to the nearest land mass in the positive direction along the X axis.

Bit 0 always remains a 0, and all bits are shifted right during each analysis leaving bit 1 a 0 when no class 1 reliability observations are used for a grid intersection.
Number of Observations - The total number of current observations used in the analysis of the new optical thickness for the grid intersection.

Bits/PixelUser option for the data delivery format. Indicates the number of bits to be used to represent each sensor pixel value in the delivery file. Choosing 8 or 16 bits/pixel results in the unpacking of the sensor data and the placing of each pixel value into the indicated number of bits. Note that the sensor data originates in a packed format with each pixel value occupying 10 bits. If 8 is chosen, the least significant of the original 10 bits are discarded. If 16 is chosen, the original 10 bits are preserved and are packed into a 16-bit word. Choosing 8 or 16 bits/pixel also allows users to select which combination of channels they want in their delivery files. Choosing 10 bits/pixel results in the data being delivered in the original packed format with all 5 channels. Users cannot perform channel selection if they choose 10 bits/pixel. Back to the top | ||||||||||||||
Channel NumberUser option for the data delivery format. The channel number, or band, of the instrument that acquired the data. Channel numbers are associated with different wavelengths or ranges of wavelengths within the electromagnetic spectrum. Users may choose which combination of channels they wish to receive in their delivery files if, and only if, they choose either 8 or 16 for the bits/pixel value.

Back to the top | Datatype
The data types available for AVHRR are:
Full Resolution Area Coverage (FRAC): AVHRR FRAC data, the user may choose 1 km or 4 km as their default, available in swaths typically covering roughly an orbits worth of data. FRAC data is available for all areas of the globe and is available for data from the METOP satellites.
Global Area Coverage (GAC): AVHRR data at the reduced 4KM resolution, available in swaths typically covering roughly an orbits worth of data. GAC data is available for all areas of the globe.
High Resolution Picture Transmission (HRPT): Limited area AVHRR data at the full 1KM resolution, available in swaths typically covering roughly 12 minutes worth of an orbit. HRPT data is only available for areas of the earth scanned by the sensor while the satellite is within range of a receiving station.
Local Area Coverage (LAC): Limited area AVHRR data at the full 1KM resolution, available in swaths typically covering roughly 12 minutes worth of data. LAC data is recorded on-board the satellite and transmitted to a receiving station once the satellite is within range of the station. Because of limitations in the amount of data that can be stored on the satellites recorders, LAC data is limited and the acquisition of the data is scheduled. Back to the top | ||||||||||||||

Back to the top | ResolutionFor LAC and HRPT, the instantaneous field-of-view (IFOV) of each channel is approximately 1.4 milliradians (mr) leading to a resolution at the satellite subpoint of 1.1 km for a nominal altitude of 833 km. This is generally referred to as 1 km resolution. Since GAC data contain only one out of three original AVHRR lines and the data volume and resolution are further reduced by averaging every four adjacent samples and skipping the fifth sample along the scan line, the effective resolution is 1.1 x 4 km with a 3 km gap between pixels across the scan line. This is generally referred to as 4 km resolution.
For AVHRR FRAC data, the user may choose 1 km or 4 km as their default.
For the other AVHRR datatypes, the resolution is fixed and cannot be changed. The values are 1 km for LAC and HRPT, and 4 km for GAC. Back to the top | ||||||||||||||

GOES Satellite Data GVAR_B11 (Block 11) | | BandsSynonymous with channel number. The channel number, or band, of the instrument that acquired the data.

Bits/PixelUser option for the data delivery format. Indicates the number of bits to be used to represent each sensor pixel value in the delivery file. Choosing 8 or 16-bits/pixel results in the unpacking of the sensor data and the placing of each pixel value into the indicated number of bits. Note that the sensor data originates in a packed format with each pixel value occupying 10 bits. If 8 is chosen, the original 10-bit raw data is reduced to 8 bits/pixel. If 16 is chosen, the original 10 bits are preserved and are packed into a 16-bit word.
User interface note: Users can specify bits/pixel in the formatting of their extracted data. Selections 8 and 16 are for unpacked extraction and allow users to subsequently specify which channels they wish to receive. If users specify raw data, they will receive all channels in the original 10-bits/pixel format. Back to the top | ||||||||||||||

The meaning of times varies within this data family. For GPSP1, the date/time means start time of first data point. Temporal search will be based upon that field. For the TLEs, it means create time, which will be the basis of a temporal search for that type. For the POEs and MOEs, the three times in the file name mean create, start of validity and end of validity. Temporal search will be upon the validity time range. Back to the top | ||||||||||||||

Where:
PROCESSING-CENTER = Processing-Center where the data were created. Length: 3 char. Domain:
“NPR” = NOAA/NESDIS Product – Suitland, Maryland, USA
PROJECT-ID = I dentifies the project name. Length: 4 Char. Domain:

Length: 6 char. (5 characters for the date string, plus one for the “D” at the beginning). Domain: “D”+”YYJJJ”
START-TIME = e.g. “S1355”, where “S” identifies this group as a start time delimiter. “1355” denotes 13 hours 55 minutes UTC (to the nearest minute) and represents the time at which spacecraft recording began.
