1. Unit Standardization:
|
|
|
145 |
A preliminary step in the preprocessing pipeline involved the standardization of units across both datasets.
|
146 |
This was imperative to ensure a uniform unit system, facilitating a seamless integration of the datasets in later stages.
|
147 |
The units in both datasets were scrutinized and amended to adhere to a common unit system, thereby eliminating any discrepancies that could hinder the analysis.
|
148 |
|
149 |
2. Coordinate System Rectification:
|
|
|
150 |
The coordinate system of the datasets was rectified to ensure a coherent representation of geographical information.
|
151 |
Specifically, the coordinates and dimensions were renamed to a standardized format with longitude (lon) and latitude (lat) as designated names.
|
152 |
The longitude values were adjusted to range from -180 to 180 instead of the initial 0 to 360 range, while latitude values were ordered in ascending order,
|
153 |
thereby aligning with conventional geographical coordinate systems.

3. Grid Interpolation:
|
|
|
156 |
The ERA5 dataset is structured on a regular grid with a spatial resolution of 0.25º, whereas the CERRA dataset inhabits a curvilinear grid with a Lambert Conformal

157 |
projection of higher spatial resolution (0.05º). To overcome this disparity, a grid interpolation procedure was initiated.
|
158 |
This step was crucial to align the datasets onto a common regular grid (with different spatial resolution), thereby ensuring consistency in spatial representation.
