-------------------------------------
EC5503D_AER_an2007_SSS_REG_PROFILE_allsky_v2_FM3.ps.txt
= Nighttime all sky CALIOP version 2

EC5503D_AER_anYYYY_SSS_REG_PROFILE_allsky_v3.ps.txt (YYYY=2007,2008,2009)
= Nighttime all sky CALIOP version 3 (= the ones used for the model evaluation)

EC5503D_AER_an2007_SSS_REG_PROFILE_ allsky24h_v3.ps.txt
= 24h all sky CALIOP version 3

EC5503D_AER_an2007_SSS_REG_PROFILE_cloudfree_v3.ps.txt
= Nighttime cloudfree CALIOP version 3

“SSS” is the season (DJF, MAM, JJA, SON, ANNUAL)
“REG” is one of the 13 following regions:

The EC5503D_AER*PROFILE*.txt file consist in 10 columns:
(5. and 6. = Profiles and Observations used for the model evaluation).
1. Altitude (km)
2. EC532_AER (km-1)= extinction for the raw data
3. N_AER = N. of CALIOP observations for the raw data
4. NLayer = N. of aerosol layers for the raw data
5. EC532_AER_filt (km-1) = extinction after all screenings and cloud mask 
6. N_AER_filt = N. of CALIOP observations after all screenings and cloud
mask
7. NLayer = N. of aerosol layers for the screened data
8. to 10. = the same than 5. to 7. but for clouds (not used/not checked).
