Zusammenfassung |
In this paper, the atmospheric precipitable water (PW)
over the area of Cyprus was estimated by means of Advanced Very High
Resolution Radiometer (AVHRR) thermal channels brightness temperature
difference (ΔT). The AVHRR derived ΔT was calculated in a
grid of 5 × 5 km cells; the corresponding PW value in each grid cell was
extracted from Moderate Resolution Imaging Spectroradiometer (MODIS) Level 2
product (near-infrared algorithm). Once the PW – ΔT
relationship coefficients corresponding to the area of Cyprus were
calculated, the relationship was applied to AVHRR data for one month period.
Radiosonde derived PW values, as well as MODIS independent PW values were
used to validate the estimations and a good agreement was noted. |
