Sensitivity of Antarctic surface climate to a new spectral snow albedo and radiative transfer scheme in RACMO2.3p3 Christiaan T. van Dalum, Willem Jan van de Berg, and Michiel R. van den Broeke Institute for Marine and Atmospheric Research, Utrecht University, Utrecht, the Netherlands Correspondence: Christiaan T. van Dalum (c.t.vandalum@uu.nl) Received: 17 September 2021 – Discussion started: 30 September 2021 Revised: 28 January 2022 – Accepted: 1 February 2022 – Published: 29 March 2022 Abstract. This study investigates the sensitivity of modeled atmosphere (Etourneau et al., 2019). Several Antarctic heat surface melt and subsurface heating on the Antarctic ice sheet records have been broken in the past decade (Bozkurt et al., to a new spectral snow albedo and radiative transfer scheme 2018), with an all-time record for continental Antarctica of in the Regional Atmospheric Climate Model (RACMO), ver- 18.4 C observed at the tip of the Antarctic Peninsula (AP) sion 2.3p3 (Rp3). We tune Rp3 to observations by perform- in February 2020 (WMO, 2020). These higher temperatures ing several sensitivity experiments and assess the impact on have led to increased TI - Comment on tc-2021-298 DO - 10.5194/tc-2021-298-rc3 DA - 2021-11-04 UR - https://www.deepdyve.com/lp/unpaywall/comment-on-tc-2021-298-cBLfOX0iNf DP - DeepDyve ER -
