Corrigendum: “An Attempt to Retrieve Continuous Water Vapor Profiles in Marine Lower Troposphere Using Shipboard Raman/Mie Lidar System”

Abstract

The authors of Katsumata et al. (2020) (hereafter KTN2020) have discovered an error to process the lidar data. The error is on the length of the raw data bin along the ray direction (hereafter “bin length”) at a part of the channels to archive Raman backscattered signals. KTN2020 erroneously set the value as 7.5 meters at all wavelengths in both MR15-04 and MR17-08. The correct bin length is 3.75 meters, for data at 607 and 387 nm (for nitrogen) in MR15-04 and MR17-08, and for data at 660 and 408 nm (for water vapor) in MR17-08. Meanwhile at 660 nm (for water vapor) in MR15-04, correct bin length is 7.5 meters as identical to that in KTN2020. The differences between correct bin length and those in KTN2020 are summarized in Table C1. These errors came by confusing specifications of hardware used before and after 2015 (i.e. before and after adding capability to receive Raman signals). Note that the error was only for the Raman signals, while the other data (at Mie scattering channels) were unaffected.
