ATM Surface Height Data (DMS Level) Our Rapamycin MedChemExpress DMS-based lead detection benefits is usually employed to cross-validate sea ice freeboard items derived from IceBridge Airborne Topographic Mapper (ATM) Level 1B data [23]. The ATM is an airborne conically scanning laser altimeter having a wavelength of 532 nm. A laser pulse is emitted in the ATM at a price of 5 kHz, and it has 1 m of footprint at a typical 500 m altitude above the surface. Because ATM covers exactly exactly the same place and time together with the DMS images having a smaller sized cross-track width ( 400 m), DMS photos are usually utilized as great reference for Setanaxib In Vitro extracting the ATM-based freeboard data [32,33]. Within this study, the ATM information are resampled within a 2 m grid and projected to the same projection program as DMS (NSIDC sea ice polar stereographic North) to match the geographical location. Following retrieving thin ice and leads via DMS pictures, we geographically linked the leads with the ATM data to extract freeboard variations along the Laxon Line, and examine with freeboard information derived from SILDAMS (Sea Ice Lead Detection Algorithm) [23,32]. 2.three. Oceanic and Atmospheric Geophysical Parameters NSIDC supplies sea ice motion data (nsidc.org/data/NSIDC-0116) using a spatial resolution of 25 km on the Equal-Area Scalable Earth grid [34]. This sea ice motion vector is derived from many data sources, which includes AVHRR, AMSR-E, SMMR, SSMI, SSMI/S satellite sensors, International Arctic Buoy Program (IABP) buoys, and also the Na-from SILDAMS (Sea Ice Lead Detection Algorithm) [23,32]. 2.three.
