Hi, I have multiple rasters named as follows for each year. But, I need to calculate mean for weekly ONLY for 09, 10 and 11 months based on the following week definition. Week 1: Day 01, 02, 03, 04, 05, 06 Week 2: Day 07, 08, 09, 10, 11, 12 Week 3: Day 13, 14, 15, 16, 17, 18 Week 4: Day 19, 20, 21, 22, 23, 24 Week 5: Day 25, 26, 27, 28, 29, 30, 31 Can anybody suggest me a way to process months 9, 10 and 11 in one go for the following script.?

OK, have a look at the following code: from datetime import datetime , timedelta , date def main ( ) : import calendar import os # locations and naming name_template = 'prism_ppt_us_30s_{0}.bil' ws =

to work with 6 days in each week?) and you have 15 "weeks" in those 3 months. When it is a leap year the start ordinal (it's not really Julian) will be 244 otherwise it will be 243 (following your code). If you need the rasters including the path (work space) you can un-comment line 32 and comment line 33. On line 35 you would perform your cel statistics to calculate the mean. I noticed that you have raster in the BIL (band interleaved by line) format. I assume that each raster has a single band?

Thanks again. Weeks should be defined by the Julian day of the year. Please take a look at my revised code above. Hope you can understand. For example, if year is 1998 then September 01 to September 06 (Julian days are from 243 to 249. I need to revised my above code if I have all the files in one folder (Test_ONLY). My code above does the job but I need to change years and month after each run and replace the files in the Test_ONLY folder for the corresponding year. I would like to place all the files (From 1998 to 2016) in Test_ONLY folder and automate the process above. Hope this helps to understand.

Thanks for the reply, but I'm still not completely sure how the weeks should be defined: I just ran a small snippet of code: import calendar for month in range ( 9 , 12 ) : print "\n" , calendar . month ( 1998 , month ) Which prints: September 1998 Mo Tu We Th Fr Sa Su 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 October 1998 Mo Tu We Th Fr Sa Su 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 November 1998 Mo Tu We Th Fr Sa Su 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 How will your weeks in this case be defined?

nav[aria-label="Primary Navigation"] { padding: 0; & ul { list-style: none; width: 100%; display: flex; flex-direction: row; justify-content: start; align-items: start; gap: 30px; padding: 0; & li { margin: 0; } & ul li { list-style: none; } } }

Loop over rasters to calculate mean values for weekly

DuminduJayasekera

Hi,

I have multiple rasters named as follows for each year. But, I need to calculate mean for weekly ONLY for 09, 10 and 11 months based on the following week definition.

Week 1: Day 01, 02, 03, 04, 05, 06

Week 2: Day 07, 08, 09, 10, 11, 12

Week 3: Day 13, 14, 15, 16, 17, 18

Week 4: Day 19, 20, 21, 22, 23, 24

Week 5: Day 25, 26, 27, 28, 29, 30, 31

Can anybody suggest me a way to process months 9, 10 and 11 in one go for the following script.?

Thanks in advance,

my bad, I used "isoweekday" (1 to 7) on lines 16 and 26 and used the definition (0 to 6) which corresponds to the definition used by "weekday". Change isoweekday to "weekday" and you will get this result:

So there are a few years that will have 13 weeks (13 mean rasters) and the rest will have 14 weeks. Is that what you are after or do you want to have a fixed number of weeks?

It would be good to learn something more about the definition of the weeks from months 9 till 11. Should these start on Sunday or Monday or what day? In different years you may end up with a different amount of weeks that "intersect" with those 3 months.

Look at the code below:

<SPAN class="keyword token">def</SPAN> <SPAN class="token function">main</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">:</SPAN>
&nbsp;&nbsp;&nbsp; <SPAN class="keyword token">from</SPAN> datetime <SPAN class="keyword token">import</SPAN> date<SPAN class="punctuation token">,</SPAN> datetime<SPAN class="punctuation token">,</SPAN> timedelta
&nbsp;&nbsp;&nbsp; <SPAN class="keyword token">from</SPAN> calendar <SPAN class="keyword token">import</SPAN> monthrange

&nbsp;&nbsp;&nbsp; <SPAN class="comment token"># settings foro years and months</SPAN>
&nbsp;&nbsp;&nbsp; years <SPAN class="operator token">=</SPAN> range<SPAN class="punctuation token">(</SPAN><SPAN class="number token">1998</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="number token">2017</SPAN><SPAN class="punctuation token">)</SPAN>

&nbsp;&nbsp;&nbsp; <SPAN class="comment token"># Let's assume that a week starts on Monday (0) and ends on Sunday (6)</SPAN>

I just noticed that in some case (2003, 2008 and 2014) the last date is including November 30st. Will check in that, but the idea is to get a clearer definition of what you mean with the week that are part of months 9 to 11.

Thanks Ian for the reply. The file names are as follows:

prism_ppt_us_30s_19980101.bil

prism_ppt_us_30s_19980102.bil

prism_ppt_us_30s_19980103.bil

prism_ppt_us_30s_19981231.bil

These files are in H:/Test_ONLY folder. I have years from 1998 to 2016.

Hope this helps.

Could you give some examples on how you named the files? I feel like if they are named in a uniform easy to parse manner it would fairly simple to make separate lists for years and months and weeks and then use them as input for Cell Statistics.
