In 2000, NASA launched the Earth Observing1 (EO1) Advanced Land Imager (ALI) to test new technology that could improve the TM/ETM+ sensor series, yet ensure Landsat data continuity. The study reported here quantified the continuity of satelliteretrieved surface reflectance () for the three most recent Landsat sensors (Landsat-4 TM, Landsat-5 TM, and Landsat-7 ETM+) and the EO-1 ALI sensor. The study was based on grounddata verification and, in the case of the ETM+ to ALI comparison, coincident image analysis. Reflectance retrieved from all four sensors showed good correlation with groundmeasured reflectance, and the sensortosensor data continuity was excellent for all sensors and all bands. A qualitative analysis of the new ALI spectral bands (4p: 0.845-0.890 um and 5p: 1.201.30 um) showed that ALI band 5p provided information that was different from that provided by the ETM+/ALI shortwave infrared bands 5 and 7 for agricultural targets and that ALI band 4p has the advantage over the existing ETM+ nearinfrared (NIR) band 4 and ALI NIR band 4 of being relatively insensitive to water vapor absorption. The. basic conclusion of this study is that the four sensors can provide excellent data continuity for temporal studies of natural resources. Furthermore, the new technologies put forward by the EO1 ALI sensor have had no apparent effect on data continuity and should be considered for the upcoming Landsat8 sensor payload.
