Is it my ordering mistake or just the available dataset is like that ?
Users are advised that ASTER SWIR data acquired from April 2008 to the present exhibit anomalous saturation of values and anomalous striping. This effect is also present for some prior acquisition periods. Please refer to the ASTER SWIR User Advisory Document for more details. https://lpdaac.usgs.gov/documents/217/A ... _18_08.pdf
Please let us know if you have any further questions.
The Terra satellite was launched on December 18, 1999.
ASTER SWIR detectors are no longer functioning due to anomalously high SWIR detector temperatures. ASTER SWIR data acquired since April 2008 are not useable, and show saturation of values and severe striping. All attempts to bring the SWIR bands back to life have failed, and no further action is envisioned. VNIR and TIR data continue to show excellent quality, meeting all mission requirements and specifications.
LP DAAC offers nearly 1.5 million global ASTER Level 1A scenes and related on-demand products. The vast majority of these scenes were acquired prior to the SWIR detector temperature increase, and SWIR bands present may be used in investigations: https://lpdaac.usgs.gov/news/aster-user ... y-14-2009/
