Gold Level 1C Limb data

ResourceID
spase://VSPO/NumericalData/SES-14/GOLD/L1C/LIM/PT4S

Description

The Level 1C limb data is sampled on a uniform angular grid Latitude.
The data is resampled as follows:
* About 4 scan mirror positions to fill the 0.2° L1C bin.
* Narrow slit width: 0.075°
* 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
* 30 bins Altitude
* 32 bins N-S
