EXPERIMENT: Fortaleza/CE

LIDAR level 2 - CLOUD height and width layer
The files are encoded in ASCII, tab-separated values, resolution: 1 minute, 7.5m vertical. - There is no header.

- if there are no clouds
DD-Mon-YYYY <SPACE> hh: mm:ss <TAB> -99
- otherwise
DD-Mon-YYYY <SPACE> hh: mm:ss <TAB> alt<TAB> alt_value1<TAB>..<TAB> alt_valueN<TAB>width<TAB>widthvalue1<TAB>....<TAB>widthvalueN<CRLF>


Example:

29-Apr-2011 09:13:53    -99
29-Apr-2011 09:14:54    alt    675    width    60
29-Apr-2011 09:15:54    alt    247.5         637.5    width    60         112.5
29-Apr-2011 09:16:55    alt    247.5           645    width    52.5           105

First line: there is no cloud measured by the LIDAR at the 09:13:53, day 29-Apr-2011.
Second Line: there is ONE cloud layer, at height 675m above the LIDAR, with a width of 60m.
Third Line: there are TWO layers,the first at 247.5m above the LIDAR, with a width of 60m,  the second at 637.5 m above the LIDAR, with a width of 112.5m.
