Hi Susan,
I wanted to catch you up on our call with Karl yesterday. We made the
following decisions, pending your approval:
1) Do away with the Babase 2.0 raw Farenheit weather data
column/records collected for the min_max records. These records have
already been converted to Celsius and exist in our excel sheet as such.
Precision and accuracy documentation on them is sketchy so we gain
little by converting the current C records back to F, storing the raw F
records in the database, and then having Babase run a program to read
everything as C.
2) Do away with the "Baboon Camp A: lower gauge" records that were kept
for ~6 months to compare the upper and lower thermometers. I will keep
these comparison files in a separate excel sheet, but Babase will hold
only records for the Baboon Camp B upper gauge. (see further notes on
the station abbreviations below).
3) Using an aerial photograph, Jeanne showed me the 4 approximate
locations that temp gauge has had within the current camp. The naming
of these station is confusing but here is the rough outline of a support
table we propose to incorporate into Babase (the first 5 rows). The
view people should use to browse the data will only show the station
abbreviations. We chose the alphanumeric combination to show that the
min_max gauge has moved 4 times within the current Baboon Camp. Can we
get your input on the names and the proposed deletion/renaming of the
upper and lower gauge values (see notes below)?

OT Ol Tukai
BC1 Group Ranch Campsite A located just S of the current (2008)
kitchen cabin within the Baboon Camp
BC2 Group Ranch Campsite B located just N of the current (2008)
kitchen cabin within the Baboon Camp
BC3 Baboon Camp A located about halfway between the current (2008)
kitchen cabin and the current (2008) weatherhawk station within the
Baboon Camp
BC4 Baboon Camp B Located ~10 m S/SW from the current (2008)
weatherhawk station within the Baboon Camp
Baboon Camp B: upper gauge this station distinction will be eliminated
and the station will simply be "Baboon Camp B"
Baboon Camp B: lower gauge These records will be removed from the
min_max table in Babase but kept in a separate file if someone wants to
compare.
4) For sporatic missing times, Karl will run a little program to
calculate the average time of reading for that month and use this to
populate the empty field. Where there are months or year of missing
times ('71-'76), Jeanne proposed to fill the empty fields with 07:00.
We will have a new column in the weather tables to indicate that these
are estimated times. It will be called "est. time" and be filled in as
Y or N.
5) The current weather tables have a rg_span column that does a
calculation to tell the span of time between rain gauge readings. Using
an estimated time will created an estimated values in this column so we
need another column to indicate where these estimates occur. This new
column will be "est rg_span".
6) We need to build a "Users Guide to the Min_Max_Rain data" because
there is a good deal of support documentation that users need to read,
but it doesn't fit into the scope of Karl's technical documents, current
field protocols, or data management protocols. Any ideas about where to
keep this (the wiki perhaps?)
I think that's all for now.
Many thanks,
Tabby
