Rolando: As per our phone conversation this morning, the species we need for the lower boundary of timesgcm (30 km) are: h2o, h2, co, co2, h, oh, o, o3, ho2, no2, no2, no, ch4 I'll wait to hear from you after you talk with Susan. I assume that you can give us code that accesses your archives, rather than giving us the numbers directly. Then we will run the code initially to get the data for solstice and equinox conditions.
