Interactive comment on “Satellite passive microwave measurements of sea ice concentration: an optimal algorithm and challenges” by N. Ivanova et al
The authors would like to thank Dr. J. C. Comiso for the valuable comments that helped improving quality of the paper. We will address the comments point-by-point (the answers are marked by A). General Comments: 1. The primary objective of this study is to evaluate the performance of several sea ice concentration algorithms, identify the strengths and weaknesses of a selected few and come up wi...
متن کاملImproving passive microwave sea ice concentration algorithms for coastal areas: applications to the Baltic Sea
Sea ice concentration can be retrieved from passive microwave data using the NASA Team algorithm or the Artist Sea Ice (ASI) algorithm, for example. The brightness temperature measurements obtained from the Special Sensor Microwave Imager (SSM/I) instrument or the Advanced Microwave Scanning Radiometer-EOS (AMSR-E) are commonly used for this purpose. Due to the coarse resolution of these instru...
متن کاملEnhanced Sea Ice Concentrations from Passive Microwave Data
1. Introduction Sea ice concentration is usually defined as the fraction of ice covered area within an observational field, which in our case is the footprint of the satellite sensor. This assumes that the ocean surface is binary, i.e., either ice covered or ice free. With the binary characterization of the ice covered surface in mind, ice concentration can be quantified from satellite instrume...
متن کاملAntarctic sea-ice extents and concentrations: comparison of satellite and ship measurements from International Polar Year cruises
Antarctic Sea Ice Processes and Climate (ASPeCt) ship-based ice observations, conducted during the Sea Ice Mass Balance in the Antarctic (SIMBA) and Sea Ice Physics and Ecosystem eXperiment (SIPEX) International Polar Year (IPY) cruises (September–October 2007), are used to validate remote-sensing measurements of ice extent and concentration. Observations include varied sea-ice types at and ins...
متن کاملThin Ice Area Extraction in the Sea of Okhotsk from Gcom-w1/amsr2 Data
Passive microwave radiometers on-board satellites can penetrate clouds and can monitor the global sea ice distribution on daily basis. The authors have developed an algorithm to extract thin ice area in the Sea of Okhotsk from the passive microwave sensor AMSR2 on-board GCOM-W1 satellite. The algorithm uses the brightness temperature scatter plots of AMSR2 19GHz polarization difference(V–H) vs ...
