Gold Level 1C Day Disk data

ResourceID
spase://NASA/NumericalData/GOLD/L1C/NI1/PT16S

Description

The Level 1C NI1 data is sampled on a uniform angular grid of 0.15° in both Longitude and Latitude. The data is resampled as follows:
* About 4 scan mirror positions to fill the 0.15° L1C bin.
* Use center of L1B and L1C bins to resample (nearest neighbor) GOLD Public Science Data Products Guide (1.0) 26
* Spectral data is combined within a L1C bin WITHOUT doing any wavelength alignment
for each L1B sample
* 51 bins E-W
* 100 bins N-S

Name
East/West Grid values
ParameterKey
GRID_EW
Description

The East/West grid values.

Caveats
The coordinate system for the images is not strictly geographic. EW refers to roughly the east and west geographic directions on the surface of the Earth but specifically east and west of the nadir direction.
