可用的土壤水分数据介绍
- 土壤湿度数据一般有两种。
1、再分析数据(基于监测的数据和模型驱动的)
ERA-Interim 和 MERRA-2
2、基于卫星反演(ESA CCI)
ESA CCI

SM. Because of the lack of global in-situ SM observations, we used daily SM data from reanalysis and satellite retrievals.
- The reanalysis products are ERA-Interim and Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2).
- The satellite product is the European Space Agency’s Climate Change Initiative (ESA CCI), and we used the combined SM data set (v04.4).
- For ERA-Interim, with a spatial resolution of ~80 km, the SM content of the soil layers between 0m and 1m is summed up (weighted by the thickness of each layer).
- For MERRA-2, with a spatial resolution of 0.625° × 0.5°, the root-zone SM content is provided and thus used.
- For ESA CCI, with a spatial resolution of 0.25°, satellites can only sense the thin (0.5–5 cm) surface soil layer.

- 注意:
数据集很多(有小时,每天和月均),别下错了。
里面的子集也很多,选择需要子集下载就行,全下的话,一个文件300mb,太大了。

soil moisture(ESA CCI)-SMOS
European Space Agency’s Climate Change Initiative (ESA CCI)
在这项研究中所使用的数据可以通过ESA CCI SM项目现场(访问http://www.esa-soilmoisture-cci /),欧洲航天局的CCI开放数据门户网站(http://cci.esa.int/data)和Earth2Observe水循环积分器(https://wci.earth2observe.eu /)。

SMOS,SMAP,AMSR2
- SMOS(The Soil Moisture and Ocean Salinity)
- 博客: SMOS数据产品介绍与下载方法(https://wwwblogs/yhpan/p/10913591.html)
The Soil Moisture and Ocean Salinity (SMOS) 卫星是欧空局发射的一颗以探测地球土壤水含量以及海表盐度为目标的卫星,
卫星所搭载的唯一载荷为Microwave Imaging Radiometer using Aperture Synthesis (MIRAS微波成像综合孔径辐射计)。
