Revision C. March 2008. The Japan Aerospace Exploration Agency (JAXA) initially hoped to be able to launch the successor to ALOS during 2011, but this plan did not materialize. where the availability was limited (e.g., because of the requirement A destriping process (Shimada & Isoguchi, 2002, 2010) was applied On October 9, 2020, 23:25:00 UTC, the satellite flew by Seasat over Antarctica.

Masanobu Shimada, Takuya Itoh, Takeshi Motooka, Manabu Watanabe, Shiraishi Tomohiro, Rajesh Thapa, and Richard Lucas, "New Global Forest/Non-forest Maps from ALOS PALSAR Data (2007-2010)", Remote Sensing of Environment, 155, pp. For each year and location, In 2008, it was announced that the images generated by ALOS were too blurry to be of any use for map making. Earth Engine is free to use for research, education, and nonprofit use. PRISM; AVNIR-2; PALSAR The global 25m PALSAR/PALSAR-2 mosaic is a seamless global SAR image created by mosaicking strips of SAR imagery from PALSAR/PALSAR-2. Advanced Land Observing Satellite (ALOS), also called Daichi (a Japanese word meaning "land"), is a 4-ton Japanese satellite launched in 2006. [4][5] Then, JAXA announced the problem was solved. selected from the year before or after, including from 2006. Vexel Corporation. In cases The DN values can be converted to gamma naught values For each year and location, the strip data were selected through visual inspection of the browse mosaics available over the period, with those showing minimum response to surface moisture preferentially ... JAXA/ALOS/PALSAR/YEARLY/SAR, PALSAR has advanced functions and performance of the synthetic aperture radar on-board the first Japanese Earth Resources Satellite (JERS-1). for observations during specific emergencies), data were necessarily Backscatter values may vary significantly from path to path [10][11], In April 2011, the satellite was found to have switched itself into power-saving mode due to deterioration of its solar arrays. Anyone wishing to publish any results using the datasets should clearly acknowledge the ownership of the data in the publication. The launch had been delayed three times by weather and sensor problems. On 22 April 2011, the ALOS satellite was lost due to a power anomaly and completed its operations phase. ALOS was launched from Tanegashima, Japan, on 24 January 2006 by H-IIA rocket No. SAR, Palsar Algorithm Description.

PALSAR: Phased Array type L-band Synthetic Aperture Radar, which enables day-and-night and all-weather land observation: Advanced Land Observing Satellite (ALOS), also called Daichi (a Japanese word meaning "land"), is a 4-ton Japanese satellite launched in 2006.

ALOS, Advanced Land Observing Satellite, is the world's top class land observing satellite launched in January 2006 by Japan Aerospace Exploration Agency (JAXA) and carries a nickname "DAICHI" Detail about ALOS ALOS three different sensors.

Revision L, July 2009. ALOS mission objectives set by JAXA were to: The mission included optical and an active L-band SAR sensor payload whose high-resolution data may be used for environmental purposes. then return to this page. 13-31, December 2014. doi:10.1016/j.rse.2014.04.014.
