Retrieval from C-band SAR shows similar performance, but C-VV is more suitable than C-HH to derive vegetation height (RMSEs of 48 and 56 cm respectively). An exponential relationship with in situ height was evident for all tested parameters (NDVI, TC, C-VV and C-HH) suggesting that ...
The height was just enough for the team to experience three to four minutes of weightlessness and enjoy dramatic views of the earth’s curvature. The spacecraft then turned around and glided back through Earth’s atmosphere. It landed flawlessly at the same New Mexico runway...
in height, the wings step back in a spiral configuration, changing the building’s shape at each tier and so reducing the effect of the wind on the building. The central core emerges at the tower’s top and is finished with aspire, which reaches more than 700 feet (200 meters). The ...
