Along with similar multispectral bands used on the Landsat 7 ETM+ sensor, the addition of a new coastal/aerosol band and a new cirrus band provides improved data products. Two thermal bands (TIRS) capture data with a minimum of 100 meter resolution, but are registered to and delivered with the OLI data product.
Landsat 8 file sizes are larger than Landsat 7 data, due to additional bands and improved 16-bit data product. Landsat Level 1 Products are delivered in a tar.gz compressed file:
|LDCM/Landsat 8||1 GB||2 GB|
