10 th INTERNATIONAL CONFERENCE ON URBAN CLIMATE - ICUC10 6-10 August 2018, New York, NY, USA Session 6A: Urban Climate Processes VI (Paper no. 6A.7A) PREPROCESSING ALGORITHM QC alhorithm consist two stages: - logical cleaning Ta – higher than 50 o C, less lower then -30 o C; min and max thresholds for all 12 months. - internal dynamical cleaning (with two iterations) Iteration 1. If the condition | 𝑢𝑗𝑘 − 𝑢𝑗 − 1 𝑘 | > 𝜁 𝑏𝑜𝑒 | 𝑢𝑗𝑘 − 𝑢𝑗 + 1 𝑘 | > 𝜁 is satisfied, 𝜁 = 3 o C Iteration 2. min 𝑘𝑙 = 1,2… 𝑢𝑗𝑘 − 𝑢𝑗𝑘𝑙 > 𝜁 Haversine formula: used to determine closest stations. Missing values: interpolation only if less than 6 consecutive missing values.

10 th INTERNATIONAL CONFERENCE ON URBAN CLIMATE - ICUC10 6-10 August 2018, New York, NY, USA Session 6A: Urban Climate Processes VI (Paper no. 6A.7A) CONCLUSIONS 1) Monitoring (2014-2017) Ta values in different LCZs 2) Focus on extreme periods 3) 17 air temperature sensors in urban area of Novi Sad – NSUNET 4) Highest Ta values in LCZs 2, 5, 8 and 3; lowest in LCZs A and 9 5) Highest differences between LCZ 2 and A 6) Generally, Ta and UHI intensity decreasing as follows: LCZ 2/8 � 5 � 3 � 6 � 9 � A 7) Contribute to define hot spots and when Ta pick appears 8) Contribution to urban planning strategies.
