Windows系统中下载Earthdata数据 2

从NASA数据中心下载CH2O数据时，步骤：

wget for Windows

1.Make sure you have setup your Earthdata account.

2.Install wget if necessary.

A version of wget 1.18 complied with gnuTLS 3.3.3 or OpenSSL 1.0.2 or LibreSSL 2.0.2 or later is recommended.

3.Create a cookie file.

This file will let you download GES DISC resources without having to re-login.

1. 1. Open a run-command window by pressing WinKey + R
   2. Next, enter "cmd" in the text field and click "OK"
   3. Navigate to the directory you wish to create the cookies file in. In this guide, we place it under the C drive, but any directory will do. You can navigate to the C drive by entering C:
   4. Finally, enter NUL > .urs_cookies.
      Note: you may need to re-create .urs_cookies in case you have already executed wget without valid authentication.
      Note: you can get 'Access denied' error. Enter 'dir' to verify that '.urs_cookies' file is listed in your directory.

注：在命令行里输入NUL > .urs_cookies 可能会出现如下，拒绝访问，

 

 但别担心看下URS_Cookoies（至于这个是啥，你们可以自己百度，内容太多，哈哈）在你的主目录下没？打开你的用户地址看下，

 此外，可设置以管理员身份运行，但还是会出现 【拒绝访问】：

1、打开cmd所在目录C:WindowsSystem32(操作系统分为32位和64位，视个人情况选择)，找到cmd.exe，右击打开属性; 

2、点击右下角的“高级”;

3、勾选“用管理员身份运行”，并点击确定;

4、再打开cmd，重新输入命令并执行即可。

    4. Download your data using wget:

wget --load-cookies C:.urs_cookies --save-cookies C:.urs_cookies --auth-no-challenge=on --keep-session-cookies --user=<your username> --ask-password --content-disposition <url>

1. • --auth-no-challenge may not be needed depending on your version of wget
   • <your username> is the username belonging to your Earthdata account
   • <url> is the link that points to a file you wish to download or to an OPeNDAP resource.
   • Your Earthdata password might be requested on the first download
   • If you wish to download an entire directory, such as this example URL, use the following command:

     wget --load-cookies C:.urs_cookies --save-cookies C:.urs_cookies --auth-no-challenge=on --keep-session-cookies -np -r --content-disposition <url>

To download multiple data files at once, create a plain-text <url.txt> file with each line containing a GES DISC data file URL. Then, enter the following command:

wget --load-cookies C:.urs_cookies --save-cookies C:.urs_cookies --auth-no-challenge=on --keep-session-cookies --user=<your username> --ask-password --content-disposition -i <url.txt>

 

######################################################请注意如下##########################################################

先将目录转到wget和 txt目录下   例如 cd C:Users

wget --load-cookies C:Users.urs_cookies --save-cookies C:Users.urs_cookies --auth-no-challenge=on --keep-session-cookies --user XXX --password XXX --content-disposition -i subset_OMHCHOd_003_20201012_222507.txt
