    I created this experimental AMSR2 sea ice lead data product while waiting for boarding on Kapitan Dranitsyn. ftp://ftp.awi.de/incoming/lkalesch/MOSAIC/

    This midnight visitor to the remote sensing site was not really trained to operate the SSM/I radiometer of . Fortunately, the bear just changed the elevation angle of the 37 GHz feedhorn and did no further damage. Image retrieved by M.Huntemann.

    Wow, this is a game changer for reproducible climate model data analysis! Just tried it and it works fast. Thanks for your great effort. Now I have to think about Arctic amplification for precipitation changes 🤔

    The icebreaker Kapitan Dranitsyn arrived at Polarstern. Two faint lights seen from space with Day/Night Band 0.7 µm of JPSS VIIRS.

    Very glad to read the news and see the pictures from about the remote sensing site: The Ohio State University microwave radiometer UWBRAD (with its cone shaped antenna on the left) got into operational measurement mode today.

    Trends of November Arctic sea ice thickness/extent are hardly significant when calculated over the last 10 years, the period. In contrast, the much longer record, based on SSM/I-type sensors, shows a dramatic decline of ice extent since the 1980s.

    By the way, the Ku/Ka-radar is just measuring thin sea ice with frost flowers ❄️❄️❄️ 👍😊 (photo: , )

    Polarstern is on the drift for a year through the Arctic Ocean. A comparison of the publicly available air temperatures shows it was much colder 125 ago on the Fram which was used for the first drift expedition of this kind.

    The sea ice in the Chukchi Sea still refuses to grow. satellite data clearly shows the general trend in the seasonal cycle: the sea ice melts earlier and grows later.

    Apologise, I like your great vizualisations but this is wrong. Greenhouse gases like CO2 and CH4 absorb in the thermal infrared: they influence the outgoing thermal emission. The jetstream is not driving everything. Maybe involved but causality is elusive Graph by
