QC alhorithm consist two stages:

  • logical cleaning

Ta – higher than 50oC, less lower then -30oC; min and max thresholds for all 12 months.

  • internal dynamical cleaning (with two iterations)

Iteration 1. If the condition | 𝑢𝑗𝑘 − 𝑢𝑗 − 1𝑘 | > 𝜁 𝑏𝑜𝑒 | 𝑢𝑗𝑘 − 𝑢𝑗 + 1𝑘 | > 𝜁 is satisfied, 𝜁 = 3oC Iteration 2. min𝑘𝑙 = 1,2… 𝑢𝑗𝑘 − 𝑢𝑗𝑘𝑙 > 𝜁 Haversine formula: used to determine closest stations. Missing values: interpolation only if less than 6 consecutive missing values. PREPROCESSING ALGORITHM

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 5369A 7) Contribute to define hot spots and when Ta pick appears 8) Contribution to urban planning strategies.
