您可以使用Cartopy库的Robinson投影来绘制SST(海表温度)图像。以下是一个简单的示例代码:
```python
import cartopy.crs as ccrs
import cartopy.feature as cfeature
import matplotlib.pyplot as plt
# 数据准备(示例数据)
lons = [100, 110, 120, 130, 140] # 经度
lats = [20, 30, 40, 50, 60] # 纬度
sst = [[25, 26, 27, 28, 29], # 海表温度数据
[24, 25, 26, 27, 28],
[23, 24, 25, 26, 27],
[22, 23, 24, 25, 26],
[21, 22, 23, 24, 25]]
# 创建地图投影
proj = ccrs.Robinson()
# 创建画布和坐标系
fig = plt.figure(figsize=(10, 6))
ax = fig.add_subplot(1, 1, 1, projection=proj)
# 绘制地图边界和海岸线
ax.coastlines(resolution='50m', linewidth=0.5)
ax.add_feature(cfeature.BORDERS, linewidth=0.5)
# 绘制SST图像
im = ax.pcolormesh(lons, lats, sst, transform=ccrs.PlateCarree())
# 设置颜色刻度条
cbar = plt.colorbar(im)
# 设置标题和坐标轴标签
ax.set_title('SST Map')
ax.set_xlabel('Longitude')
ax.set_ylabel('Latitude')
# 显示图像
plt.show()
```
请注意,这是一个简单的示例代码,您可以根据您的实际数据和需求进行相应的修改和优化。
