Hindcast of the alkalinity addition field trial in Halifax Harbour, Canada (Fall 2023) – Sensitivity tests: Air-sea flux

The dataset provides a sensitivity test (15% change in air-sea flux) to the simulation of the alkalinity addition experiment that was carried out in the Halifax harbour in the Fall 2023. The model couples circulation with inorganic carbon chemistry and includes tracers to simulate the fate of the alkalinity addition (particulate and dissolved phases) and its effects on inorganic carbon parameters and air-sea CO2 fluxes in the Halifax Harbour and the inner Scotian Shelf. Results of the 6-month simulations (October 1, 2023 to April 1, 2024) were used to determine the sensitivity of the hindcast to air-sea flux.

该数据集提供了一种敏感性测试（空气-海面通量变化15%），以模拟2023年秋季在哈利法克斯港进行的碱性物质添加实验。模型将环流与无机碳化学相结合，并包含示踪剂以模拟碱性物质添加（颗粒和溶解相）的命运及其对无机碳参数和哈利法克斯港及内斯科特浅滩空气-海面CO2通量的影响。利用2023年10月1日至2024年4月1日的6个月模拟结果，以确定对空气-海面通量的回溯模拟的敏感性。
